Yeah i wrote it by myself. it's really strange... i feel like it got stuck with this symbol i mean gold eventhough there is not any specified symbol for this i used "_Symbol" so on any chart it works...there is not any complex code in it . it opens a buy or sell position in like every 500 points....

I know buddy it's my final code and wanna put it on market and it's supposed to only work on Gold but this Automated Validation is checking it on different pairs so i kinda got stuck in this :(
