MQL4 - Lesson 7 - Notes

You can access Jim Dandy's MQL4 youtube course here for free. He also has a website with videos here and here. These are my notes of lesson 7:

Leverage Info

• double leverage = NormalizeDouble((Bid/margin/100))*1000,0);

Buttons for message box 

• message box is an integer
• flags used after last comma in message box separated by pipe symbol
• message box can be used to detect if the ea is on the right timeframe -> int message… ->if (message ==3)messagebox("You pushed …) <- look for correct number (timeframe, symbol) ->yes/no

Write our own function

• start function calls another function -> has to send along some information-> int start (XXX)
• e.g. ordersend function -> sends back number, true/false, … -> return (XXX)
• programm = series of function calls
