Metatrader4 bug hunt
на первый взгляд : в твоем индикаторе буферы не просчитываются, хотя и объявлено целых два, а в эксперте ты хочешь получить значения из этих буферов, а так здесь так много наворочено, что с ходу даже при желании трудно разобраться :)

Eto kuski koda, v katorovom u menia eti oshybki vylezli, na return() nismotri - sami funkciji po sebe v skompilirovannom MQL ploxo obrabatyvajutsia. Kompilirujetsia bez oshybok.
Gdie tam stack overflow ili 4to nibut' poxoze - tol'ko Metaquotes s debugerami MT4 mozet uznat' :-)
Privet,
Pokapalsia ja jies4io nad etim crashlogom i vot 4to uvidel:
Jiesli v biblioteke ispolzujetsia "extern bool variable;" - srazu crash!
vot moj kod biblioteki posle otslezovanija:

Popravtie peredavajemyje global'nyje peremennyje na biblioteki MQL4 tak kak eto inogda nuzno peredavat' 4erez stack. 4erez GlobalVariableSet/Get - ni samyj lu4yj sposob dlia etoj situaciji, potomu lu4e iz indikatora takovo vroda sdelat' biblioteku.
Budu zdat' fixa :-)
Vot jies4io narvalsia na 1 oshybku:
Kokda ObjectCreate() sidit v biblioteke mql4 kak 4ast' funkciji, objety tipa arrow iz eksperta nirisujetsia kokda vyzyvaju etu funkciju.
