Take profit depending on market

[bollitori]

Hello,

My idea is to obtain the diference between the upper and lower band of bollinger; and then put this value as take profit. This is because the market has diferent volatility along the day, and bollinger could be an acceptable value on pips of volatility.
A better option is to use a "VaR value" like this http://www.oanda.com/forex-trading/anal ... calculator , because is more accurate; but I don't know how to implement this.
My shared ea to understand better my idea is: https://fxdreema.com/shared/GKmqi33xe

Actually, I'm thinking just to put a fixed value because it goes well, but possibly a take profit could depends on volatility. I don't like trailing stops because the backtest don't perform well.

Thanks,
Bye.

The difference between two price levels as a value I call "price fraction". You probably got the value and it is multiplied by 0.9, but then in "Sell now" you selected "Fixed pips", which is not correct in this situation, because you have value similar to 0.0023, not 23. Select "Custom (price fraction)" instead.
