Consecutive Bullish Candles Function logic problem

New comment
 

Hi ,, 

I appreciate your help for the below function that search in a range to extract the most number of bullish candles and return the first candle in the trend with an exception of maximum 2 bearish candles , in other words , if there were 7 candles in uptrend and there were 2 maximum bearish candles in between  it will ignore them and return the start of the bullish trend 

below is the code I am trying but getting only1 , it is a robot and there is a button to execute the function

Say THX and take the idea created by Vladimir Karputov to get the counts of Bull-Bear bars from 1 to 7 ( except the current bar, and i added some lines to comment the counts of B/S's ) 

i added lines with labelled "...MNS" to show the counting results within the original source code. such as Comment("Count/Body of B/S for Last 1-7 bars "+ string(cnt_B)+" ("+DoubleToString(bodyB/_Point,0)+") - "
        +string(cnt_S)+" ("+DoubleToString(bodyS/_Point,0)+")");  // printing counts/Body added by MNS
