Day trading strategy: a rules-based plan you can finish by the close

What day trading is

Day trading is a holding period, not a single technique: you open and close every position within the same trading day. Nothing is held overnight, so you never pay swap and never wake up to a gap through your stop. In exchange you need several hours of attention on the days you trade, and you take more trades than a swing trader, so you pay more in spreads.

Day trading sits between scalping, where trades last minutes and target a handful of pips, and swing trading, where trades last days. A typical day trade on a major pair risks 10 to 25 pips and aims for 20 to 50. That makes costs noticeable but not dominant, which is why many traders find it a workable middle ground. The comparison is set out in full in day trading vs swing trading.

Most day trading strategies are variations on three ideas: trading breakouts from a defined range, trading pullbacks inside an intraday trend, and fading moves at strong levels. The plan below uses the first, with a retest entry that keeps the stop tight. Related approaches have their own pages: the opening range breakout and the VWAP strategy.

The routine before the session

A day trader's results are decided as much by the twenty minutes before the open as by the trades themselves. Do the same things in the same order every day, ideally before 07:00 UK time for the London session:

1. Check the calendar. Note every high-impact release for the currencies you trade and its time. A jobs report at 13:30 means no new trades from about 13:00 to 13:45. Our page on how forex prices move explains why releases matter.
2. Mark yesterday's high and low on the 15-minute chart. Add the Asian session's high and low if they are close by.
3. Read the 1-hour chart for bias. If the last few days have made higher highs and higher lows, you prefer breaks of the high. If price is in the middle of a wide range, you accept either side.
4. Write down your risk: the cash amount per trade and the daily loss limit. Decide them now, while nothing is at stake.

The setup: previous day high break and retest

The previous day's high and low are among the most watched prices in any market. Stop orders from short sellers sit just above the high, and breakout buyers place entry orders there too. When London trades through the level, those orders fill together and often push price well beyond it. The plan tries to join that move after the market has shown the break is real.

1. The break

A 15-minute candle must close beyond the previous day's high (for a long) or low (for a short). A wick through the level is not enough; you need the close.

2. The retest

Price usually comes back to the level it broke within a few hours. Old resistance at the high now acts as support. Wait for price to return to within a few pips of the level.

3. The trigger

Enter when a 15-minute candle closes back in the breakout direction off the level. If price instead closes back inside the old range, the break has failed and there is no trade.

In the chart above, GBP/USD spends the Asian session under the previous day's high at 1.2735. London breaks it, runs to 1.2752, and pulls back. The retest low is 1.2733, two pips under the level, and a bullish candle closes there. Entry is 1.2740, the stop is 1.2726, back inside the old range, for 14 pips of risk, and the target is 1.2768, twice the risk.

Stop, size and exit

The stop goes a few pips beyond the retest low for a long, which normally puts it back inside the previous day's range. If price trades there, the breakout has failed and the trade has no reason to exist. On GBP/USD this usually means 12 to 25 pips; on EUR/USD a little less; on gold, a few dollars.

Size every trade from that stop. With a $5,000 account and a 1% risk, you have $50 to lose. A 14-pip stop on GBP/USD, at about $10 a pip per standard lot, gives 0.35 lots. A 25-pip stop on the same account gives 0.2 lots. The position size calculator does it in seconds, and the number should be ready before the trigger candle closes.

For the exit, a fixed target at twice the risk is the simplest version and the easiest to test. A 2 to 1 trade breaks even at 33% before costs. With a 1.5-pip cost on a 14-pip stop, a winner nets 26.5 pips and a loser costs 15.5, which moves break-even to about 37%. If the next obvious level (an Asian high, a round number) is nearer than 2R, use that level as the target, or skip the trade if it is closer than 1.5R.

Two exits apply to every trade. First, flat by the close: anything still open at 20:00 UK time is closed at market, whatever its profit or loss, because holding it would make it a swing trade without a swing trader's stop. Second, the daily loss limit: after a loss of 2% in a day, or two full losing trades, stop for the day. The limit is there for the days when the market is not offering your setup and you start taking trades that only look like it.

When it fails: false breaks and dead afternoons

The breakout that does not hold is the main risk of this plan. Price spikes through yesterday's high, triggers the stops and breakout orders above it, and then falls straight back into the range. Traders who bought the spike are now trapped above the market, and their exits push price lower still. This is a liquidity sweep, and it is the reason the plan waits for a close and a retest instead of buying the first touch.

In the chart, the wick pokes nine pips above the level at 1.2735, but the 15-minute candle closes back below it. No close beyond the level means no break and no trade. The traders who bought the wick were stopped out as price fell to 1.2698.

The other failure is time. Breakouts that start late in the New York afternoon often run out of buyers before they reach a target, and you are forced to close at the end of the day anyway. Take no new trades after about 17:00 UK time. Be wary of Mondays, when there is no fresh previous day's range of any size, and of the days before major holidays, when liquidity thins out.

Finally, the behaviour risk: a day trader sees dozens of moves each session, and it is easy to tell yourself that a break of some other level is just as good. It may be, but it is not the strategy you tested. Log those trades separately, or better, do not take them.

How to backtest this day trading strategy

The rules are mechanical enough to test by hand in an evening or two:

1. Pick one pair, GBP/USD or EUR/USD, and go back six months on the 15-minute chart.
2. For each day, mark the previous day's high and low before looking at that day's candles.
3. Step forward bar by bar. Record each close beyond a level, each retest, each trigger, and the result under the rules, including closing at 20:00.
4. Charge every trade your real spread and commission, and record the days with no trade as well; they are part of the strategy.

Aim for at least 60 trades. Then look at the average win against the average loss, the longest losing streak, and the worst week. If a losing streak of eight trades would break your daily or weekly limits, adjust the risk per trade now, with the drawdown calculator, rather than in the middle of the streak.
