Sile Si:

Okay, that's what I do.

Then I compare the transaction id with the position ticker, and I think I've selected the transaction,

but it returns the price of the position. Why?

Question for the back of my mind: do you use

PositionGetDouble(POSITION_PRICE_OPEN)

Do you get the price of the trade? Or is it still the price of the position?

Alexey Kozitsyn:

Question for your enquiries: with the help of

Do you get the transaction price? Or is it still the price of the position?

Well, if I have preselected a trade, then it is the price of the trade. I could not find the opening price in the documentation.

How do you select the trade? What function?

After all, there is no trivial way to determine the opening price of a trade (not a position) in MT5. In particular cases it is possible (when a deal by parameters coincides with a position), but there is no universal way.

Choosing a deal by id

DEAL_POSITION_ID

Identifier of the position, in the opening, modification or closing of which this deal was involved. Each position has a unique identifier, which is assigned to all deals made on the symbol during the position's lifetime.

In the tester, the average price is considered correct. On the real account it shows someone else's price in the comment.

On accounts like Netting, the position and trade are different concepts. You have just shown us the position selection.

How in mql5 to find the maximum for N bars? Similar to iHighest

What's wrong with iHighest?

[Alexey Viktorov]

In mql5 how to find the maximum value of N bars? Similar to iHighest

CopyHigh into an array andArrayMaximum into this array.

This will be the maximal value, unlike iHighest which returns the index of the bar with the maximal value.
