Hi
I am interested in learning MQL coding I have read the documentation provided and need clarification.
Can someone go over the essentials of EA and Indicator coding. I am enrolling in a C# class at present.
To get some idea of the structure of a standard Expert Advisor, let us take a look at the description given below:
1. Initializing variables
2. Initial data checks
check the chart, number of bars on the chart
check the values of external variables: Lots, S/L, T/P, T/S
3. Setting the internal variables for quick data access
4. Checking the trading terminal – is it void? If yes, then:
checks: availability of funds on the account etc...
is it possible to take a long position (BUY)?
open a long position and exit
is it possible to take a short position (SELL)?
open a short position and exit
exiting the Expert Advisor...
5. Control of the positions previously opened in the cycle
if it is a long position
should it be closed?
should the trailing stop be reset?
if it is a short position
should it be closed?
should the trailing stop be reset?
It turns out to be quite simple (loloolol ok), only 4 main blocks.
Now let us try to generate pieces of code step by step for each section of the structural scheme:
