Help me control the scale of the chart from the keyboard.

The chart window is manually created, I don't know what object name to use inObjectSetInteger, I decided to do it through ChartObject.mqh to be sure.

In onchartivent I write

CChartObject object;  

      if(lparam=='9')
        Print(object.SetInteger(OBJPROP_CHART_SCALE,0,4));

In the log I get false. How can I beat this?

extern variables - what are they?

is not a constant incumbent. There is only one in 4.

1 The condition is too vague to help...

2 Use different "magiks"

Let me try to explain.

A buy signal has been triggered.

I open a BUY, SELLSTOP is set at the level of its STOPLOSS.

If BUY is closed by TAKEPROFIT, we wait for the next entry signal.

If the price hits the STOPLOSS order and SELLSTOP triggers, then BUYSTOP is being placed at the STOPLOSS level. And so on, until the last order closes in the open position. In other words, we roll back and forth.

What does series two mean?

[Forallf]

MakarFX:
What does the second series mean?

We start a series of reversal orders (like in the previous post), which will end up with a winning order.

But before the first series is completed, there may be a new signal to BUY or SELL. We should enter the market based on a new signal according to the known principle (the second order series is launched).

There may be a third and a fourth one. The second one should be dealt with)

like this, but without orders ( SELLSTOP - BUYSTOP ) as soon as the position closes, it opens in the opposite direction (the first position has to be opened manually)

Thank you. I have seen such Expert Advisors. But I have a need for one with stop orders. And for mt4.

Do you want help or an EA?

I suggested it - it's up to you to decide. - It may be useful for someone.
