Execute orders on indicator alerts

I have bought the following indicator https://www.mql5.com/en/market/product/103515?source=Site+Market+MT5+Indicator+Rating006, which has some Buffers (info: https://www.mql5.com/en/blogs/post/754629). 

I want to be able to execute orders whenever these Buffers are triggered. But i want to be able to choose on which buffers orders to execute. ex. In one chart i might want to execute orders when Trend Breakout catcher is triggered. On another chart i might want to execute orders when MTF Trend Finder is triggered. 

Buffers:

Trend Breakout catcher:
SetIndexBuffer(0,UpSignal);
SetIndexBuffer(1,DnSignal);

SetIndexBuffer(4, buyexit)
SetIndexBuffer(5,sellexit);

Smart trailing Stop:
SetIndexBuffer(8,arrup,INDICATOR_DATA);
SetIndexBuffer(9,arrdwn,INDICATOR_DATA);

MTF Trend Finder:
SetIndexBuffer(10,TrendUp,INDICATOR_DATA);
SetIndexBuffer(11,TrendDown,INDICATOR_DATA);

Smart Cloud:
SetIndexBuffer(15, Buy_Signal, INDICATOR_DATA);
SetIndexBuffer(16, Sell_Signal, INDICATOR_DATA);
