ANDREY:
Good afternoon, everyone.
The code below encodes a simple idea.
If the last closed order was on SEL
If the last closed order was on the NEL
Open a NEL order

if (OrderSelect (Ht-1,SELECT_BY_POS, MODE_HISTORY))                                            
if ( OrderType ()==OP_SELL)                                            
X = OrderProfit( );                                            

if (OrderSelect (Ht-1,SELECT_BY_POS, MODE_HISTORY))                                            
if ( OrderType ()==OP_BUY)                                              
if(X < 0)                                              

OrderSend(Symbol(),OP_SELL,0.1,Bid ,3,Ask+400*Point,Ask-200*Point,"17-10",123 );

QUESTION
What language construct can be used to add two more conditions to this code (circled in red)

If the last closed order is NEL
If the last CEL order closed
If the last closed order has closed on the NEL
If the last closed order has been closed through the NOR

Thank you for your help.

Hello ,

Can you tell me if MT5 has a coordinate system on the charts ?

Is it possible to edit the built-in standard indicators in MT5?

***

Yes, they do - they are pixels. There is a whole group of graphical objects that uses pixels as coordinates when drawing. There's also a canvas - a canvas that you can draw with pixels.

No, you can't, but all built-in indicators have their own open-source analogues: \MQL5\Indicators\Examples\.

Honestly, I meant the X-axis and Y-axis coordinate system,

Do you know where I can read about the pixel structure?

Thanks for the link to the source code!

To be honest I meant the coordinate system of X-axis and Y-axis,

Can you tell me where I can read about the pixel device?

That is, there is vector X and vector Y, and that is what we need to know,

Thanks for the links, I will study it.

Hello forum members,

I need to get time series from ZigZag indicator, which will correspond to minima and maxima of this indicator, but as far as I know, I can only get double data from the indicator. Is it possible to do it easily and efficiently?
