I stumbled upon a blogger who shared a strategy that can be used either with MT4 charts or with web based...netdania, freestockcharts or any other chart out there what lets you set indicators.
She uses 5 min timeframe, and adds indicators (Bollinger Bands, RSI (70; 30), Stochastic Oscillator (80;20) and (CCI) Commodity Channel Index)
So for 15 min exp. time PUT trade, the candlesticks have to cross BB upper border, RSI has to be 70 or higher (or very close to 70), the Stochastic should be over 80 and crossed to the right side or crossing and the very important indicator CCI should be above 150. The CCI is supposed to show extreme conditions and the blogger said that she never takes a trade if the CCI is lower than 150.
For the CALL trade, it's all opposite, candlestick has to cross the Bollinger bottom border, RSI has to be 30 or lower, CCI has to be at least -150 or lower and stochastic has to be below 20 and crossed to the right or crossing.
The trade should be taken at the beginning of next candlestick that meets the strategy signals (check the picture).
It's also important to check the economical news, so do not trade close to the news affecting any of the currency from the pair.
If anybody has an interest and my explanation wasn't clear enough, send me a PM and I can share the youtube video link.
