In the video above, I want to introduce you to and make you to get the feel of using the MQL4 Doc reference website.
Because most of the time you will spend more time here while you code. If you can remember all the library functions/methods provided by the MT4 then it's good for you. When you are used to programming with MQL4, you will remember most of the function that you often use.

In this video I try to implement bits of particular trading strategy from here http://forextradingstrategies4u.com/...ding-strategy/.
The strategy is related to Simple Moving Average and Candle price.
In this video I also show you how to make an if else condition statement in order to define a downtrend or an uptrend according the strategy above.

In this video I teach you about For and While Loop operator. This is very important basic concept and most likely you will use this more often in all your indi/EA program.

In the next video I will teach you about VARIABLE, and 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 now I have teach you the basic only.
Those are the brick and mortar which you then can use to make your own skyscraper.
You need to master the brick and mortar (be the master mason) before you make your pyramid.

Sure buddy!

Yeah we need to cover up some basic first before we go further.

I really appreciate if you could start get your hand dirty. If you are in problem with your code, you can let me know so I can help you with the troubleshooting.

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