This is simple and easy-to-execute, but (like all steadily profitable trading methods) it requires plenty of patience and discipline.
It's particularly good for rewarding patience and discipline, and for demonstrating that "simple" can also be "steadily profitable".
This method trades EUR/USD and/or GBP/USD during the daytime (UK time): don't enter trades before 8.30am or after about 8.00pm; we're covering most of the UK and US sessions.
Start the day with an M15 chart, draw obvious horizontal lines of support/resistance, and retain them on the M5 charts (draw any further obvious lines of S/R there, too) from which you enter and manage the trades. On the M5 charts, add a standard 14-period RSI indicator with "overbought" and "oversold" marked at 70 and 30.
Enter long at the start of the next bar when the price reaches a line and prints a pin-bar (with the point of the pin at the bottom and either nearly reaching or just crossing the line) and the RSI is below the 30-line; enter short when the converse happens and the RSI is above the 70-line. The pin-bars don't quite have to be "perfectly formed" but their opens and closes must have a distance between them of no more than 20% of the bar's length.
And now the important part: trade management. Each day, until you've banked 24 pips for the day, use a fixed target of 12 pips and a fixed stop-loss of 8 pips for each trade. After this, use the same method but without a fixed target, and when the trade's moved 12 pips into profit, move the stop-loss up from -8 pips to breakeven, and/or from there use a trailing stop of about 12 pips, to see if you can catch the occasional "runner". Don't do this until you've banked 24 pips for the day.
You should find an average of 3 - 4 good trades per day, with this method. (That means there'll be some days without even 2 good trades). If you find many more than that, then something's seriously wrong and you're not using enough patience and discipline to await only the best trades.
Risk no more than 2% of your account on each trade.
