Support and Resistance Trading

The same price level. Every time.

A trader watching EUR/USD for the first time with no knowledge of its history might look at the chart and see randomness. A trader who had been watching for three months would see something completely different. They would see a level that the market had collectively agreed to treat as a ceiling, a price where sellers consistently appeared in size, where the balance of supply and demand repeatedly shifted against further progress.

This is what support and resistance is. Not a mathematical formula. Not an indicator output. A price level where enough market participants are watching and acting that their collective behaviour creates real buying or selling pressure every time price approaches.

Previous highs and lows are the most straightforward significant levels. A price that marked the highest point of the last major rally will attract sellers if price returns to it, traders who bought near that high and then watched price fall will look to exit at breakeven when price returns. This accumulated supply at previous highs creates resistance.

Round numbers, levels ending in 00 or 50, attract disproportionate attention because traders, banks, and corporations naturally place orders at clean, convenient prices.

Previous resistance levels that have been broken become support. This is called the flip. Before the break, sellers defended the level. After the break, those same sellers have been forced out and the buyers who pushed through the level will support it on any pullback. The psychology has reversed at the level, supply has become demand, and the level now holds in the opposite direction.

The more times a level has been tested and respected, the more significant it is for future interactions.

The approach in a range is straightforward. Buy near the floor with a stop just below it and a target near the ceiling. Sell near the ceiling with a stop just above it and a target near the floor.

The risk-reward in range trading can be attractive. If EUR/USD is ranging between 1.0800 and 1.1000 and you buy at 1.0820 with a stop at 1.0785, your target is approximately 1.0970, a risk of 35 pips to make 150 pips.

The primary risk is the breakout. When a market has been ranging for an extended period and finally breaks decisively out of the range, the move that follows can be significant and fast. Stops placed just outside the range must be respected without exception. The moment a range break occurs, the range trading framework is invalidated and a breakout framework applies instead.

EUR/USD has been rejected at 1.0850 three times over two months. On the fourth approach it breaks through with a decisive daily close at 1.0890. Over the following week price pulls back to 1.0852. A trader who understands the flip does not see this as EUR/USD returning to resistance. They see it as EUR/USD returning to support. The former resistance has flipped. They enter long with a stop just below 1.0850. The level holds. The trade works.

The flip also explains one of the most common support and resistance mistakes, failing to update your view of a level after it has been broken. A level that was resistance before the break is not resistance after the break. It is support. Treating broken resistance as continuing resistance causes traders to take short setups at levels that are now floors, producing losses that should not happen.

In equity indices, previous all-time highs serve a unique function. Before they are broken they are resistance. After they are broken they become support, the strongest imaginable flip, because there are no longer any buyers who are underwater above this level.

In gold, round number levels like $4,000 and $5,000 have been powerful psychological levels as of 2026, attracting significant attention on multiple approaches from both sides.

In crypto, the previous cycle all-time high is the most significant resistance level in each new bull market. Bitcoin''s previous all-time high from each cycle has absorbed significant selling pressure before eventually being broken. Traders who entered after the break captured the subsequent clear-air move.
