thanks for your suggestions
I have tested this strategy by GBPUSD data since 2008.
By the default settings which I explained on post #1, this strategy makes an average profit about 600 pips per month.
Every one may test it himself by looking the chart in the past.
You are almost true that this strategy is better on trending market.
But since 2008 the market have had different situations.
So the result shows that this is a profitable strategy.
Some months we may make more money and some months less.
But the final result is satisfiable.
Most of the traders look at the chart day and night on different pairs.
They trade and trade again.
But they loose at the end of the month.
This strategy is mechanical and so simple and needs just some minutes to set pending orders on a distinct time.
But about trailing stop:
Your suggestion look like good.
But we should test it in the past, If it made our strategy more profitable, then we may use it as a rule in the strategy.
I will use trailing stop option on Expert Advisor for this strategy.
Then we can have he fast back test by different setting of trailing stop.
