I  want to share your a best trading starategy that i mostly used.
Not any indicator or strategy is final, so use other indicators and analysis with this.
it is very nice, is if anyone can help me tune it a bit more.
Currency: you can use any currency but GBP/JPY or USD/JPY will be best result oriented.

Time frame: 1M, 5M, 15M

Indicators: 3 sets of bollinger bands:
1) Period 50. Deviation 2 (RED)
2) Period 50. Deviation 3 (orange)
3) Period 50. Deviation 4 (Yellow)

Sell strategy:When price crosses the upper red band , at least half way to the orange band (if it gets to the yellow band is better but not as usual) Then the price will tend to retrace towards the center of the bollinger bands, you profit form this retracing.
Buy Strategy, it is the same as selling, the difference is that we will wait for the price to range between the lower red and yellow bands, and trade the retracing towards the center.

Tips: do not trade on ranging ,or quiet markets, do not trade previous to news releases. Go for 5 to 10 pips. Great system to trade between opening of london session and the closing of the japan session.
Stop Loss: since this strategy requires you to look at the screen (remember this is the 1M time frame) I tend to have two kinds of stops: time based and loss based.
Time based: Try and figure out how long will it take the market to get in your expected direction, if the time that you planned is already due, then close the order. No point on waiting for a loss…

Stop Loss: Since you are trading a very tight time frame your stops should also very very tight. Sometimes, you will profit from a 3 minute trade and you wont be able to set a proper S/L. So your stops will be given to you by your money management system…
What I would like to do is to study wether to add or not some extra indicators. I attach the results from my last week 102% profit, +80% of profitable trades.
