Thank you for the answer. But I still can't figure out the right formula string that calculates this, I'm not familiar with many things. Could you spell it out here like.

I miscalculated here, in addition to the profit/loss for the day I need the account balance at the beginning of the day. :((( Help))

Account balance() - changes constantly, how to fix it for example on Hour==1 ?

Profit calculation...

if you want the current day's profits, then

datetime dt=iTime(_Symbol,PERIOD_D1,0);

Tatiana Zyrianova:
Afternoon. Can you please tell whether an indicator can forcibly start the Calculate event by pressing a button on the chart that is handled in OnChartEvent?

ChartSetSymbolPeriod with the same symbol and timeframe can be used to update the chart (similar to the Refresh command in the terminal). Updating the chart in turn triggers recalculation of the indicators attached to it. Thus, you can recalculate the indicator on the chart even when there are no ticks (for example, on weekends).

Profit counting...

If you want the current day's profits, then

Not exactly what I want. I want "if PROFIT FOR THE DAY has exceeded a certain percentage (already calculated) of the BALANCE at the beginning of the day, then stop trading, or vice versa, until it has not exceeded - then trade (function already exists, too). I really hope there are some ideas.

IT IS NECESSARY TO FIND THE ACCOUNT BALANCE AT THE BEGINNING OF THE DAY!!! Accountbalance changes all the time and therefore it cannot be used, you need a formula where it is set for a certain time probably. e.g. 00:01.

Here it is, but it gives an error, help me fix it

error

  datetime TimeCheck_sb = StrToTime("1:00");
  if(TimeCurrent()==TimeCheck_sb)
     {
      AccountBalance() = sb1; sb1 = AccountBalance();
     }

I told you

AccountBalance()-GetProfitFromDateInCurrency(.....)

you need a formula that gives you the account balance as of the beginning of the day

[Порт-моне тв]

MakarFX:

I told you.

subtract the current day's profit from the current balance and you get the balance at the beginning of the day

look, the problem is that the percentage that I want to set, for example (1%) changes numerically and if

AccountBalance()-GetProfitFromDateInCurrency(.....)

at each new trade the BALANCE will increase and so will the 1%. So my function will not work because there is no FIXED SET POINT.
