[MQL4]

I spent many hours, and I cannot solve the problem to this code:

if (MODE_ASK==121.10)

{

ticket=OrderSend(Symbol()..............

I want the USD\JPY to trigger a buy at this point. What's wrong with this code?

Also, can someone tell me a code syntax that will trigger a buy at a certain time?

Thank You. God bless You.
