LangLang's Trading Principles · The Rules His Course Keeps Coming Back To

Trading principles distilled from LangLang's course, each with his own words and the lesson segments that teach it, flagged against the latest weekly market review. Updated every week.

Market state in the latest weekly review (2026-w43): BTC ranging, platform strategy in profit, many trades. Read that weekly review

• Trade with the trend only — If the higher timeframe is bullish, only look for long opportunities; even if you see a short setup, don't take it. Counter-trend trades aren't illogical, but you don't know where the real reversal will start, so you have to try repeatedly and get stopped out repeatedly. A trend-following entry starts when it starts at a structure convergence point; the win rate and risk-reward ratio are on a completely different level.（taught in 14 sections · fits the latest week）
• No logic, no trade — Before opening any trade, you must clearly explain the logic: what timeframe you're in, why you're taking this direction, and where the target space is. In review, losing trades are basically those with unclear or wrong logic. Trades with logic also vary in quality; only good logic deserves heavy position and long holding.（taught in 21 sections · fits the latest week）
• Define cycle direction first, then entry — Analyzing any market has two steps: first, use timeframe and logic to decide whether to trade, long or short, and where the space is; second, find the turning point and structure on a smaller timeframe to enter. The order cannot be reversed; no entry technique can save a trade with the wrong direction.（taught in 19 sections · fits the latest week）
• Split positions and use low leverage — Position management has two core rules: split funds into multiple parts and don't go all-in at once; keep leverage per position low. No matter how many mistakes, the equity curve stays smooth thanks to the fault tolerance from splitting positions. Whether your mindset is stable ultimately depends on position management.（taught in 17 sections · fits the latest week）
• Place stops at effective key levels — Stop-loss is not a fixed percentage, but placed where if hit, it means the direction is invalid short-term, usually below the turning point or start level. Only with a light position dare you place the stop at an effective level; heavy positions will get washed out by volatility midway, and even if you're right, you won't make money.（taught in 29 sections · fits the latest week）
• Stop and review when tilted — After a few consecutive losses, it's easiest to reverse, chase, or take weird trades; this must be resolutely avoided. If you notice you're tilted, stop first, review, and write a trading plan for today; ten minutes can bring you back. You don't notice distorted actions at the moment, but in review you see them at a glance.（taught in 12 sections · fits the latest week）
• There is no god in trading — Even those who understand the market deeply will have their mindset disturbed, get tilted, and make mistakes; the key is to keep losses within a controllable range and adjust back as quickly as possible. Trading techniques can be learned; the real difficulty is overcoming your own human nature.（taught in 3 sections · fits the latest week）
• Persist in review and reflection — Review regardless of good or bad performance; persistence will surely bring progress. The method is simple: take historical market data bar by bar forward, think clearly about what structure was before, how it will go after, and where to go long or short. Loving reflection and summary is a necessary condition for making it.（taught in 10 sections · fits the latest week）
• Grasp the big, let go of the small — Big levels, big cycles, big logic are 'big'; which turning point to enter, a few points difference in stop-loss are 'small'. If the big direction is right, small details can be rougher; if a big trend comes but you can't find a perfect entry, get on board with a light position first. Details are done according to your own personality; the final result can be good.（taught in 2 sections · fits the latest week）
• Trial with small stops when direction is right — As long as the higher timeframe logic holds and there is space above, go to the smaller timeframe to find turning points and try; if wrong, stop and try again. The number of trials is limited, each stop is not large, and as long as one works, it covers all costs. The premise is that you truly judge there is still space and control your position so you're still in the game after a few mistakes.（taught in 11 sections · fits the latest week）
• A correct stop-loss is worth taking — If a trade with correct logic, position, and size gets stopped out, it is still a correct trade; this kind of stop-loss should be adhered to no matter how many times it's given. Whether the market moves is not up to us; what we can do is ensure we don't lose much on the way down and make money when it goes up.（taught in 14 sections）
• Buy pullback support, not high breakouts — Good buy points are almost always lower: after a box's second test of the top, enter at the pullback stabilization, not after the price breaks out. Entering at the breakout is often already high, forcing a wider stop, worsening risk-reward, and getting washed out by false breakouts. At high levels, do more support buying and less breakout trading.（taught in 15 sections）
• Trade the structure, not the price — A breakout trade is about the breakout of the whole consolidation structure, not the moment a certain price gets pierced. When the structure has converged well and a candle starts up from support below, that candle is the starting point of the breakout; waiting for price to break and then chasing is passive.（taught in 21 sections）
• Chasing means light size, wide stop — When a higher-timeframe structure is full and the expected room is large, if you missed the start you should still chase. But the stop can only go near the starting point, which is far away, so position size must drop to half of normal or even less. Chasing itself isn't the problem; chasing with heavy size is.（taught in 10 sections）
• Box phases split at second test — After a box comes down from its high, the second test of the low or the second test of the high marks the divide: before that is the early phase, after it is the late phase, where it truly starts trying to pick a direction. How it moves in between is a black box, no need to guess; wait for it to reach the prior high, pull back and hold, then watch for the breakout.（taught in 7 sections · fits the latest week）
• Few moves inside the box — Inside a box there are only two kinds of logically sound spots: the one bounce after the main up-wave ends, and the breakout after consolidation is complete. The rest of the time, trading back and forth inside the box wins sometimes and loses sometimes, with a mediocre overall win rate; a pretty structure may just be a trap.（taught in 10 sections · fits the latest week）
• Don't force profits in chop — Chop means neither bulls nor bears have the edge: it can't go up and it can't go down. Forcing profits then is like betting on a fight with no winner yet. The market spends most of its time ranging; however big the swings, a market without certainty isn't a good market.（taught in 8 sections · fits the latest week）
• Rest when capital retreats — When BTC tops out and corrects and capital is retreating across the whole market, big money isn't trading, and retail finds it even harder to make money. If good structure and good timing are given but it still can't lift, the market really has no money. The best move then is to rest and defend, and wait for the next round.（taught in 10 sections）
• Don't short just because of a top — Judging that the top will correct doesn't mean you should short: momentum is still there, so shorting is counter-trend; as it falls there are buyers catching longs all the way, so the risk-reward on shorts is poor; and you may miss the real long launch. Rather than take a lower-grade short, rest and wait for consolidation to complete.（taught in 4 sections）
• Keep counter-trend shorts modest — If you short inside a higher-timeframe bull market, know it's a counter-trend trade: don't be greedy, lower your expectations, and first analyze how many supports lie below. Take profit when there is profit, close when it feels wrong, and never hold and fight it; being bearish is one thing, whether the short actually plays out is another.（taught in 8 sections）
• Short from above, not below — When shorting with the downtrend, the entry should be at the upper edge of a bounce, not chasing a breakdown after a big drop has already happened. The good approach is to wait for it to break down, bounce, fail to bounce further and turn, then enter at the turn with the stop above it. Flip the chart upside down and you'll see whether you're actually chasing a breakout.（taught in 5 sections）
• Short the wave-5 false breakout — When an advance has completed five waves at a relatively high level, then makes a false breakout and reverses back down, forming a small platform and heading lower, that is often the end of the whole move. The premise for such a short is a high level and a weakening market environment, then find a chart to enter; it is still counter-trend, so control expectations.（taught in 7 sections）
• Leaders resonate with BTC — All crypto moves revolve around BTC: at the end of BTC's consolidation, capital starts testing altcoins; when BTC launches, the leading coin resonates; when BTC reaches a swing top, capital retreats from altcoins. So if BTC hasn't topped, the leading coin generally won't top; and every BTC rally produces an altcoin leader.（taught in 17 sections）
• Pick leaders by volume, hype, room — Don't get stuck on how to define a leader; a few things are enough: is it in a main up-wave, is volume large, is hype high, is the move big. Capital favors coins with a good daily structure and room above, clean-supply new listings, and hyped projects; if it barely drops while BTC corrects, it's a seed for the next wave.（taught in 19 sections）
• Buy the first divergence — If you missed the leading coin's launch, don't chase it. Wait for its first divergence, and when it stabilizes, bravely buy into it, using the low of the divergence as your defense. The premise is that it is indeed the leading coin and not at a high level after several waves of gains. You can trade the first and second divergences, but after two, be more cautious; don't buy the third divergence.（taught in 9 sections）
• Small divergence short, big divergence hold — He divides corrections within the main upward wave into small divergences, big divergences, and super-large divergences. Small divergences have little force; buy at the bottom and exit after a segment. After a big divergence, there is often a second wave, so you can hold if you enter. A super-large divergence means a long rest. Different levels correspond to different holding methods.（taught in 12 sections · fits the latest week）
• Wait for convergence after super divergence — After several rounds of gains, when a super-large divergence appears at a key resistance level, the consensus has been released, so in the short term, don't bet on either direction. Focus on the end of the correction: the more it converges, the smaller the amplitude, and the longer it goes without a move, the more you should watch it.（taught in 3 sections · fits the latest week）
• Run while pulling at high acceleration — After the fifth wave, a high-level accelerating market is the riskiest; it can't even withstand one correction at the top, so you must run while it's pulling and take profits when you have them, without expecting too much. After the fifth wave, going long on convergence has low reward-to-risk and belongs to the fish-tail market; a new good market definitely requires a large-level correction.（taught in 8 sections · fits the latest week）
• No adding at highs, keep base position — He basically identified the leading coin but didn't make money because adding at high levels raised the cost, and one pullback wiped out the base position, or he repeatedly reduced and added at highs. Be extra cautious about adding at highs, regardless of other reasons; without adding, many trades would not have lost overall.（taught in 9 sections · fits the latest week）
• Hold base position with cost advantage — The low-cost base position obtained at the launch point is the most valuable; many rallies without any warning are only captured by those holding the base position. With a cost advantage, endure normal pullbacks and place the stop loss near the cost to strive for greater space, rather than giving it away on a small fluctuation and then chasing it back.（taught in 5 sections · fits the latest week）
• Keep distance from market when holding — When holding a base position, staring at the screen all the time is a big taboo; after staring for a long time, your mindset gets chaotic and judgment becomes subjective, leading to random reductions and additions. After setting the stop loss, avoid watching if you can; during consolidation, you should leave the screen.（taught in 5 sections · fits the latest week）
• Take profits in stages by space and position — Taking profit is a systematic issue, depending on where you entered and the expected space. Set one or two targets and exit in batches; if unsure, exit little by little. For trades that don't resonate or are at relatively high levels, exit half first, don't hold all. When there's no resistance above, estimate targets using round numbers and the approximate amplitude of each wave.（taught in 14 sections · fits the latest week）
• Profit outside system is a trap — Making money is not always good: earning a little with methods outside your system brings bad habits, subtly making you continue to violate rules, and in the end, you lose far more than you gained. Don't touch money you shouldn't earn; the moment your intention violates the system, the outcome is already determined.（taught in 6 sections · fits the latest week）
• Impulsive scalping is draining — Scalping without logic is mostly due to itchy hands; overall it results in small gains or even small losses, and the greater cost is draining emotions and energy, setting the stage for later impulsive trades. In a market move, there are only a few logical positions; trying two or three times at each position is enough, and the rest are invalid trades.（taught in 11 sections · fits the latest week）
• Only trade spots within the system — He divides a instrument's journey from launch to end into several logical positions: launch, small divergence, second wave after big divergence, and high-level topping, shorting after the main wave ends, and rebound within a box. Among these, launch and second wave after big divergence are most worth trading; topping is counter-trend and the worst. Any other entry is considered a mistake.（taught in 10 sections · fits the latest week）
• Shrink entry conditions when losing — When things are not going well for a period, proactively set discipline for yourself, shrink all entry conditions back, and only trade points with very good logic; let go of even profitable ones with average logic. First reduce position size and let go of the obsession to break even; it's okay if the data looks bad, as long as review shows the trades themselves are fine and your mindset is stable, you are moving in a good direction.（taught in 8 sections）
• Use seasons to set attack and defense — The first dimension is always the market cycle: when there is plenty of money in the market and when there is little. Spring is when everything blooms, summer produces the strongest leading coin, autumn brings catch-up moves and many fake breakouts, and winter is completely quiet. Spring and summer call for relative aggression; in autumn and winter you contract and defend, lowering position size, leverage, trading frequency and screen-watching intensity.（taught in 16 sections · fits the latest week）
• When BTC chops, altcoins take their cue — When BTC is stuck in a lifeless range at highs, altcoins have basically no independence: they rise and fall with BTC, and their own breakouts mean little. Good altcoins have already run; most remaining breakouts are fake. Better to wait until BTC has adjusted and confirmed there is no risk, then buy in — the timing is much better.（taught in 7 sections · fits the latest week）
• Catch-up moves are weaker than the leader; be restrained — After the leading coin tops, you need to know to rest. The catch-up moves that follow are just leftover capital heat: there isn't enough money, the moves aren't smooth, which coin catches up is random, and the effect is far weaker than the leader. Once a coin's main rally is over and its bounce is done, delete it from your watchlist and wait until BTC has adjusted or the coin itself has set up again.（taught in 6 sections）
• Market environment matters more than the chart — The same beautiful structure will play out when the environment and sentiment support it, and won't when they don't — that's what being born at the wrong time means. For high-win-rate breakouts, the pattern is secondary; what matters is the market environment at the time, the logic behind it, and the higher-timeframe position. Learn to feel whether the market is hot or cold, not just look at charts.（taught in 24 sections）
• Don't take heavy positions in illiquid coins — In coins with thin order books and low volume, slippage on entry and exit eats most of the profit, and with a heavy position you can push the price down yourself and be unable to get out. A high-level breakout plus a heavy position plus poor liquidity is the most dangerous combination.（taught in 7 sections）
• If you miss it, don't chase; wait for next time — Trading is a lifelong endeavor; missing one hot theme or one move is nothing, and there will be plenty of opportunities later. If you hit your stop, accept it, reset your mindset, and wait for the market to present the next opportunity with sound logic. The market never lacks moves; what it lacks is people who have put themselves in order.（taught in 14 sections）
• Understanding it doesn't mean you should trade it — Being able to read the highs and lows, or read a box range, doesn't mean you should trade it. For the same amount of space, some paths are easy to trade and some are very hard to hold through, so pick the easy ones. Not acting is itself a form of action; the market is full of traps, and by not acting blindly you avoid many mistakes.（taught in 9 sections · fits the latest week）
• Trade small when BTC is high and risky — When BTC is at highs, neither strong nor weak, there is pullback risk; but altcoins are strong, so sitting out isn't an option either. The compromise is to look only for positions that haven't started much, use small stops and keep position size light; if you're less confident, sell half first. The worst case is chasing high and then running into a sharp BTC drop.（taught in 2 sections）
• In a weak market, see who is stronger — When the broad market corrects or drops sharply, whoever falls least and rallies first once BTC stabilizes is the direction capital endorses. Coins that are stronger than BTC during consolidation have a chance to decouple and trend on their own; the altcoin that moves first and hardest when BTC starts rising deserves close attention.（taught in 14 sections）
