Thread: MQL4 Programming

  1. #11
    In this movie I try to execute bits of specific trading egy from here http://forextradingegies4u.com/20-sm...x-trading-egy/.
    The egy is related to Simple Moving Average and Candle price.
    In this movie I also show you how to make an if else condition announcement in order to define a downtrend or a uptrend according the egy over.

    simply to add more detail into this video

    Inserted Code if(candleCloselt;sma)//Downtrend condition Print(downtrend); else if(candleClosegt;sma)//Uptrend condition Print(uptrend);

    While Loop and For operator I instruct you in this video. This is quite important concept and most likely you can use this in of your program.

    In Another video I will teach you about VARIABLE, Also FUNCTION or METHOD

    Here you can have a head start:

    Variable
    https://book.mql4.com/variables/types

    Method/function
    https://docs.mql4.com/basis/function

    Until Today I've teach you the Fundamental only.
    Those are the mortar and brick which you then can use to make your own skyscraper.
    You want to learn the mortar and brick (be the master mason) until you make your pyramid.

    Thank you for this. I've been studying trading for a month or two, but have to perform a complete time job and have kids. Hopefully I can get my EA to work to me

    Sure friend!

    Yeah we need to pay some fundamental first before we go farther.

    I truly appreciate if you were able to begin get your hands dirty. You may let me know so I can help you if you're in problem with your code.

    Learn. Don't make my videos and effort become fruitless.

    I have to emphasize here that it is very important to read through the documentation/API provided by MetaQuote or any programming language

    https://docs.mql4.com/basis/preprosessor/compilation lt;lt; there you will find info about property
    https://docs.mql4.com/basis/function/events and https://docs.mql4.com/runtime/event_fire#start lt;lt;Event handling, there you will discover beginning
