@xyon126 The problem is that that definition is very clear for a human trader. However, programming an EA to ideitify that 'V shape' can required hindreds of blocks because there can be dozens of possible combinations of candles to creare that shape. The EA need to know them all in order to ignore tha wrong ones and select only those you want.
This is why I always recommend a custom indicator doing that job. You will save a lot of pain and suffering, seriously.
