Support and resistance trading strategy: draw the zone, trade the rejection

What support and resistance are, and why they work

Support is a price area where falling prices have tended to stop and turn up. Resistance is the reverse, an area where rising prices have tended to stall. On a chart they show up as a cluster of lows, or of highs, at roughly the same level.

They work, when they do, for practical reasons rather than mystical ones. Traders who missed the last bounce from a level leave buy orders there for next time. Traders who sold at the level and saw it bounce want to get out at breakeven when price comes back. Big round numbers such as 1.2700 or 150.00 attract orders of their own. The result is a concentration of orders in one area, and that is enough to slow price down or turn it.

None of that is a law. Levels break all the time, especially after several tests. The point of a strategy is to trade the levels with the best evidence behind them, enter only when the market confirms the reaction, and keep each loss small when a level fails. For the wider basics of chart reading, our forex trading strategies guide is a good starting point.

How to draw support and resistance properly

Most trouble with this strategy starts with a cluttered chart. Use the same process every time:

1. Start on the daily chart, then move to the 4-hour. Levels visible on higher timeframes carry more weight, because more traders can see them.
2. Look for clear turns. A level needs at least two reactions where price reversed sharply and moved away by a meaningful distance, not two candles that happened to stop at the same price in a sideways drift.
3. Draw a zone. Mark it from the lowest wick to the highest candle body of the reactions (for support), or the reverse for resistance. On a major pair on the 4-hour chart, this is often 10 to 25 pips deep.
4. Prefer recent levels. A level from last month matters more than one from three years ago, unless it is a major long-term high or low.
5. Keep two or three per side. If you have drawn more, delete the ones with the weakest reactions.

Round numbers, the previous week's high and low, and the levels from the pivot point calculator make useful extra evidence when they fall inside a zone you have already drawn.

The setup: rejection at a tested zone

The strategy waits for three things in order.

1. A tested zone

Price is approaching a zone with at least two clear prior reactions. For a long trade there should be room above: the next resistance zone must be at least twice as far as your stop would be.

2. Arrival

Price trades into the zone. This is not yet a trade. Many traders buy here with a limit order, which gets a better price but takes every trade where the level then breaks.

3. Rejection

A 4-hour candle closes showing the level held: a pin bar whose long lower wick pierced the zone and whose body closed back above it, or a bullish engulfing candle. Enter at that close.

In the chart, GBP/USD has bounced from the 1.2650 to 1.2665 zone twice. On the third visit a pin bar wicks down to 1.2648 and closes at 1.2672. That is the entry. The stop goes at 1.2638, below both the zone and the wick, for 34 pips of risk. The target is the bottom edge of the resistance zone at 1.2740, 68 pips away, twice the risk.

Stop, size and exit

The stop belongs beyond the zone, not inside it: below the zone's lower edge and below the rejection candle's wick, plus a buffer of a few pips for the spread. If price trades there, the level has failed. The most common mistake with this strategy is a stop placed exactly at the level, where every overshoot and every stop hunt will reach it.

A stop beyond a zone is wider than a stop at a line, so the position must be smaller. With a $5,000 account and 1% risk you have $50. A 34-pip stop on GBP/USD costs about $340 per standard lot, so the position is 0.15 lots. The position size calculator will give you the figure for any pair.

Take profit at the near edge of the opposite zone, not its middle. Price often stalls as soon as it reaches the zone, so aiming for the far side leaves good trades unfinished. A 2 to 1 trade breaks even with a third of trades winning before costs. If the opposite zone is less than 1.5 times the risk away, there is not enough room, and you should skip the setup however good the candle looks.

When levels break, and role reversal

Every level breaks eventually, and a few warning signs show up beforehand often enough to be worth knowing.

• Repeated tests. Each visit to a level fills some of the orders waiting there. By the fourth or fifth test, there may be few left.
• Lower highs into support (or higher lows into resistance). Each bounce is weaker than the last, which means sellers are stepping in earlier. The shape is a descending triangle, and it often resolves with a break.
• Fast arrival. Price that reaches a zone in a few large candles, rather than drifting into it, has momentum that a level may not absorb.

The chart shows the pattern on EUR/USD. Support at 1.0800, a round number, holds four times, but each bounce is lower than the one before. A trader buying the fourth test is stopped when price breaks through. Then something useful happens: price climbs back to 1.0800 from below and turns down again. Old support has become resistance. This is called role reversal, and the retest of a broken level is one of the cleaner setups this approach offers, traded with the same rejection rules in the new direction.

Two more situations to avoid: a level that sits right next to a high-impact release time, where the news will decide the outcome, and a zone tested in the last few candles, where the reaction has not yet had a chance to develop.

How to backtest a support and resistance strategy

The risk in testing this strategy is drawing levels with hindsight. Avoid it like this:

1. Choose one market and go back 12 to 18 months on the 4-hour chart. Hide everything to the right.
2. Draw your zones using only the candles you can see. Redraw them once a week of chart time, never after seeing what price did next.
3. Step forward candle by candle. Record every rejection at a zone that meets the rules, with entry, stop, target and result.
4. Record the breaks too, and whether a role-reversal setup followed.
5. Charge the spread on every trade.

After 50 trades or more, compare zones with two touches to zones with three or more, and pin bars to engulfing candles. Look at the average win against the average loss and the longest losing run. The backtesting guide covers the full method, and the risk of ruin calculator helps you choose a risk per trade that survives the bad streaks.
