Unsupported Filling Mode error . but why ?

[Hakan Sari]

Hello 

I am software engineer and I code metatrader programs for 4 years. I know all syntax about metatrader5 my problem is not in syntax my problem is in anatomy.  I have some problems about metatrader 5 programming

1- why did you seperate orders as positions, orders or deals ? why did you need this illogical system ? whereas mql4 is fine. there is only orders . We can do all operations with it. I know you will say that it is complicated. there are different trading modes. but why did you mix orders ? order are orders.

2- why my orders is orders when i open, then they turn to positions. Also i cant see orders open price when i open. why ? 

3- I can open positions but i cant close them. my codes are under. I am sure my codes are working and correct. Why i cant close them. I check my symbol's filling mode  and i use it but i cant close positions even so. i will be mad.

These are really nonsensical and i am really tired to write different codes for every brokers.  whereas my mql4 codes work all brokers even backtest. it is always same. but mql5 is not.

if i am wrong tell me correct way. if you are wrong. please solve this problem. because i started to hate mql5. There is no such coding like this. you must improve metatrader not worsen. I cant adept mql5.
