IF Then code for MT4

[cpickens]

I need some help. I want to setup a If then type of situation.

I'm trying to setup a situation where I get a signal from a indicator to buy or sell then I want another set of conditions met before a trade is open regardless of how many candles it takes to happen. I know how to write a if situation but not a if then, if that's possible. Any help would be appreciated or if you can direct me to a link where I can read up in this.

Thanks

Use a global/static boolean flag.

When the conditions are met, set the bool to true.

Check for the 2nd set of conditions only when that bool is true.

Remember to re-set the bool to false when you want to start over.

Too theoretical question... maybe a pseudo-code or more explanation about your exactly doubt?  Is your problem about raw code itself or conceptual separation of "objects of decision" / event-driven decisions?
