Folks, suggest a robot. One that uses martin.
For example, I open an order and the robot keeps working...
Hello. I am trying to figure out how the events work. I have NOT worked the event of deleting an object from the chart(CHARTEVENT_OBJECT_DELETE). Removed both with the mouse and through the Object List. Build 600.
Please tell me what is wrong?
I use code from help
#define KEY_NUMPAD_5 12
#define KEY_LEFT 37
#define KEY_UP 38
#define KEY_RIGHT 39
#define KEY_DOWN 40
#define KEY_NUMLOCK_DOWN 98
#define KEY_NUMLOCK_LEFT 100
#define KEY_NUMLOCK_5 101
#define KEY_NUMLOCK_RIGHT 102
#define KEY_NUMLOCK_UP 104

Dear forum members, help me to understand, i is the current candle, why i-2 does not want to draw a line, the tester stops when running.

If you are trying to draw a line 2 candles earlier from the i, then you need to add 2, not subtract, because candle numbering goes from right to left, 0-current bar.
If you try to draw lines on a bar that doesn't exist yet (-2), the array index can't be negative. To do this, calculate the time of the needed bar, e.g. Time[0]+2*(Time[0]-Time[1])

Thank you very much, the line should have been drawn on a bar that does not exist (-2)
Thank you very much, the line should have been drawn on a bar that does not exist (-2)
Why else would there be a price. After all, the object is time-based .
Thank you very much, the line should have been built on a bar (-2) that does not exist
Please
Here is another "beautiful" solution
Time[0]+Period()*60*2 //60 переводим в секунды, 2 кол-во баров

It's not working, what's wrong?
Write code that will just open a position. That's all you need...

TakeProfit is not specified correctly in the order submission. You need to specify the price, not the number of nano-pips of profit. Correct to Ask+TakeProfit*Point()
Ask, Bid need not be normalised....
OrderSend(
Symbol(),
OP_BUY,
StartLot,
Ask,
Slippage,
0,
Ask+TakeProfit*Point(),
WindowExpertName()+" "+(string)0,

Why else would there be a price. After all, the project is being built in time.
