dictionary-like data structure

Hi, all,

How to code a dictionary-like data structure in mql? for example:

record={ myorder1: open price, open time;
myorder2: open price, open time;
myorder3: open price, open time;
..
..
}

I hope I can use ticket number as index, and it comes from a for loop,

for(int pos = 0; pos <Total; pos++)
{
OrderSelect(pos,SELECT_BY_POS,MODE_TRADES);

Thanks!

There is no such data structure in MT4.

I use parallel array technique to achieve that.

If you can explain your idea in more detail, I will see if the technique can actually helps you.

I code OCO in parallel array and embedded in my EA.

mql5 is reported to have structures, but until then parallel arrays are the only way indeed.

or you can go crazy using dlls..

Next question is do you want to use the structures?

Speed is life in MQ4 lauguage. If you don't program in a speedy fashion, the time needs to execute your essential trade order would be delayed.

Clean and effective code are as important as the strategy behind it.
