Interesting coding challenge

Hi guys,

I am drafting my own EA and is unsure how to code a specific condition.

I am using Bollinger Bands for buy and sell signals. A buy signal is triggered when the closing price of the current candle is above the upper band and vice versa for a sell signal. I have managed to code this correctly.

The condition that I please need coding assistance with is for open and pending trades to be closed when the Closing prices of two subsequent candles are below the upper band (with opened buy trades) or above the lower band (with opened sell trades).

Please can anyone assist. Will be much appreciated.

Just check the Close[1] and the Close[2] ... and compare them respectively with the BB at these 2 candles.

Thanks FerruFx. I will try the coding and if you do not mind, can you plz check it after I posted it. Thanks!

I want an EA/ROBOT based on the following indicator.I want it with the following parameters:-
1)LotSize - 1.0
2) TP - True/False

4)Initial SL - True/False
5)Initial SLPips - 60 Pips
6)Use TSL - True/False
7)TSL Pips - 20 Pips
8)Activate TSL After - 20 Pips
9)Slippage - 5 Pips

Note:THIS HAS TO WORK ON AN OFFLINE RENKO CHART.
Please help me with this because it is very important to me.Thanks in advance........
