Perhaps the best free forex trading strategy I know is the Bladerunner and combined with price action it may just be the easiest to trade.
Update 28 May 2013: the technical basics of this strategy remain unchanged, but I have started using the forex polarity indicator – a combination of the Bollinger mid-band and the 20 EMA – to trade it. There are other minor differences which you will notice if you read the Bladerunner trading blogs, but the essentials are the same: the Bladerunner remains a simple EMA trading strategy. For completeness, I give an example of trading the Bladerunner using the polarity indicator at the end of this article.
The Bladerunner is a forex price action strategy trading strategy that uses pure Price Action to find entries. We use candlesticks, pivot points, round numbers and good old support and resistance levels when trading this strategy.
No off-chart indicators (those appearing below the chart window in their own window, e.g. RSI, stochastics, MACD etc) are necessary, but you may include your favourite if you find it useful or feel more comfortable having some extra confirmation. Some people might wish to incorporate Fibonacci levels and that’s fine, too.
The only indicator I do use with this strategy is an on-chart indicator, the 20 EMA. An alternative is to use the midline of the standard 20 Bollinger bands. Either works well, in fact you can use both to trade it as a Bollinger band EMA strategy. The examples here will be using the 20 EMA.
