How to write an EA based on limit orders and close positions - MQL4 and MetaTrader 4

Scorp1978 2010.04.15 11:07 #1411

Friends !!!! I've decided to give myself another bump and write an EA based on limit orders and I will be glad for any help. I have already opened Limit orders based on Kim's functions. I am currently trying to get the average and deviations based on tick statistics(https://www.mql5.com/ru/forum/125272)(since I think they are more reliable) to open positions. We will have to implement a module to move limit orders behind the price and a module to close positions when the profit reaches a certain point.

I will write an Daily Loss/Profit limit (MT4) script for mt5 to

//op - Trade operation, order or position type. Valid values: OP_BUY,

I can't figure out what the hell this is?

I am afraid to be wrong, but clause 1.3.6.1 of the BT-08 agreement, gives the company another chance to nibble on customers.
Where can discrepancies theoretically come from ?
There are two possibilities.
The first one is that if your orders have been executed at non-market prices (you know, spikes and other failures) - the company will decide the fate of such otder and determine what is "non-market price". But this does not happen very often and is not that bad.
The second option is more important for the trader. Let's imagine that at the time of fixing, the company will widen the trading spreads. It means that on all your open positions the total profit will decrease, and this difference will be deducted from the balance. This procedure will be done by the company at the end of each trading day, and it will be like a hidden swap... No devil, no devil can stop the company from doing that... she's the CFD hostess...

Of course, everyone would like to believe in the integrity of the company and that it will not cheat like this... time will tell..., but one must find somewhere to raise funds for overseas litigation and expensive lawyers...

.....
Второй вариант более важен для трейдера. Представим себе, что на момент фиксинга, компания будет раздвигать торговые спреды. Это значит, что по всем Вашим открытым позициям суммарный профит будет уменьшаться, и эта разница будет списываться с баланса... Такую процедуру компания будет проводить в конце каждого торгового дня, - и это будет похоже на скрытое свопирование........

I'm thinking.....
Spreads do widen quite a bit every day at the sessional daily close (for those instruments where there is a break between the daily sessions, i.e. almost all commodities and futures - for our trading methodology).
It is not quite clear. In this situation, equity (funds) would decrease temporarily, but not the balance.
The positions remain open and the balance cannot change in any way.
And if this "widened" spread (when a new session is opened) is written off the balance, it is difficult to comprehend.
I have to save a DETAILED STATEMENT every evening, and scrupulously compare it with a "new balance" in the morning ...
Apparently so.

Balance = funds + total profits on open positions...

Maicl_Shuvalov 2010.04.16 11:00 #1420

And this phrase in the answer, highlighted in red, doesn't bother you ... Once again, closed trades will not be affected by this, all their figures will remain as they are. Only the final account balance is checked.
Of course, no one was going to fix the already closed positions. This would be a burglary. But they could get into open ones...
I do not have a real in B ... and I kind of do not care, but you really advise to arrange a reconciliation of the evening and morning balance ...
