How to read value of the function CheckPatternAllBullish() in class  CCandlePattern ?

I want to read it inside in void OnTick()

// Print(fican.CheckPatternAllBullish());

Error is  invalid pointer access in 'candlepatterns.mqh' (162,20)

Thanks!

Since the the error is reported at Line 162, Character 20 of the file "candlepatterns.mqh", you will need to provide that include file, or in the very least, that section of the code, for analysis.
