BreakoutSupport & Resistance Breakout
Trade the break of a well-tested horizontal level, going with the move once price closes decisively through support or resistance — ideally on the retest.

The idea
Support and resistance are the horizontal price levels where a market has repeatedly turned in the past — a floor buyers keep defending or a ceiling sellers keep selling. A breakout happens when price finally punches through one of these battle lines and holds, which tells you the balance of power has shifted decisively. The idea is intuitive: the more times a level has held, the more orders and attention cluster there, so a clean break of it releases a wave of stops and fresh entries that fuel the next move. Because these levels are the most-watched features on any chart, their breaks are among the most tradable events in all of price action. The trade-off is the false break — price pokes through, traps the eager, and snaps back — so the whole craft is separating a real break from a fake one.
The setup
Find a horizontal level that price has touched and respected at least twice, and ideally three or more times — the cleaner and more obvious the level, the better it works, because more traders are watching it. Draw it as a line across the swing highs (resistance) or swing lows (support), accepting that a level is really a small zone rather than a single price. Note the range the level caps, because its height will set your eventual target. A key concept is role reversal, or polarity: once broken, old resistance tends to become new support and vice versa, which creates the retest entry. The setup is complete when price is coiling right beneath resistance or above support, pressing on the level as though preparing to break.
Entry
There are two standard entries. The aggressive one is to buy the moment price closes decisively above resistance — a full-bodied bar, ideally on above-average volume — accepting a slightly worse price for not missing a fast move. The patient one is to wait for the retest: let price break out, pull back to the broken level, and prove it now holds as support before buying the bounce, which gives a much tighter stop and filters many false breaks. Shorts mirror the same logic on a break of support. Whichever you choose, insist on a close through the level rather than a mere intrabar wick, because the wick that pokes through and closes back inside is the signature of a trap.
Exit and targets
The most natural target is the next significant level up the chart, since that is where price is likely to stall next. A measured move — projecting the height of the range that preceded the breakout up from the break point — gives a mechanical objective when no obvious level is overhead. Many traders bank partial profit at the first target and trail the remainder behind rising swing lows or a moving average to capture a larger trend if one develops. Because breakouts can accelerate, a trailing stop often harvests more than a fixed target on the best trades. Decide the plan before entering so the noise around a fresh breakout does not push you into a rushed exit.
Risk management
The logical stop sits just back below the broken level, which should now act as support — if price closes decisively back inside the old range, the breakout has failed and there is no reason to stay. Placing the stop a little beyond the level rather than exactly on it avoids being clipped by the normal noise of a retest. Size the position so the distance to that stop is a small fixed fraction of the account, typically around one percent. The retest entry shines here because it lets you stop just under a level that has freshly proven itself, tightening risk considerably. Never chase a breakout that has already travelled far from the level, since the stop would then be too wide and the edge is gone.
Best timeframes and markets
Support and resistance are timeframe-agnostic — they work on the 15-minute chart for intraday breaks and on the daily for multi-week swings — but higher-timeframe levels are stronger because more participants respect them. The strategy applies to essentially all liquid markets: stocks, ETFs, futures, forex, and crypto all print clean, tradable levels. The best breaks come when a level has capped price for a long time and then gives way on a surge of volume, releasing pent-up orders. Illiquid names produce messy levels and frequent false breaks, so liquidity improves signal quality. When several timeframes share the same level, its break tends to be especially significant.
Common variations
A major variation is the breakout-versus-fade decision: in a strong trend you trade breaks of levels, while in a well-defined range you do the opposite and fade the edges. Some traders only take breaks that occur on a clear catalyst or volume expansion, treating quiet breaks as suspect. Round numbers, prior all-time highs, and the prior day or week high and low are popular pre-marked levels that reliably attract activity. The retest entry, sometimes called the throwback or pullback, is itself the most common refinement, trading confirmation for a better price and tighter stop. Others add a second tool — a moving average or trendline converging with the level — to grade the strength of the setup.
A worked example
A stock has been capped at 50.00 four separate times over two months, forming an obvious resistance ceiling, while support sits near 46.00 — a 4-point range. On strong volume it closes at 50.70, clearing the ceiling; rather than chase, you wait, and two days later it dips back to 50.10, holds the old resistance as new support, so you buy the retest at 50.30 with a stop at 49.30 just inside the old range, risking 1.00 per share. The measured target is the 4-point range added to the breakout, near 54.00, where you sell half. The stock trends on and you trail the rest behind rising swing lows, exiting at 55.40. The blended winner is well over 3 times the risk, and the retest entry kept the stop tight.
