Help me, problem with indicator.

 
Hi, I need help, this below is an indicator that is used to recognize certain patterns, the problem is that only recognizes the patterns that form the previous candle, but I wish that the scope of its action was around the time that take into account all the candles.
Simply put, instead of 1, in the "LOOPBACK" What should I put on making sure that the indicator takes into account all the candles?

Thank you.

WindowBarsPerChart()

but to be honest, i don't understand the purpose of using the entire chart

 
Thank you for having responded to me, I tried to enter your suggestion but to me it reports the following error:
"WindowBarsPerChart - constant expected".
 
In place of:
"// Initialization ---
    for (int shift = 0; shift <Loopback; shift ++)
     {"
What should I enter?
 
for (int shift = 0; shift <WindowBarsPerChart(); shift ++)
 
I tried to enter but when load indicator mt4 crashes.
At this point, I ask another for help.
Simply put, it could use an indicator that recognizes patterns and on a separate window, the indicator shows which currencies, the pattern has been formed.

As well as the example below.
