What is the % similarity between MQL 4 and MQL 5 ?

Yes, it seems to be the right one, thank you. Let's go and study the translator.

Where can I see a list of character codes? I can't find it.

Yes, that seems to be what we need, thank you. Let's go study the translator.

I understand you need to find max and min for n bars, then it is easier and less resource consuming to

Hello, I would like to see the code for placing orders on graphical objects provided by the indicator,

For example the indicator draws a line "N" on which an order should be placed SL-"Nsl" and TP-"Ntp".

For example, the indicator draws the line "N" on which orders should be placed SL-"Nsl" and TP-"Ntp".

If the indicator draws not buffers, but by graphical objects, then by the name of this graphical object we have to know its (object-line) price, and from this price we have to put a pending order.

The price of the horizontal line can be obtained by ObjectGetDouble(0,obj_name,OBJPROP_PRICE,0); Where 0 is the identifier of the current chart and obj_name is the name of the indicator line object.

I guess the question is too complicated...
