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.

ObjectCreate("line",OBJ_VLINE,0,Time[i-2],Open[1]);

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)

Why else would there be a price. After all, the object is time-based .

Here is another "beautiful" solution

Time[0]+Period()*60*2 //60 переводим в секунды, 2 кол-во баров

 

Folks, help me get started. Need to open an order.

input int TakeProfit = 30;

input double StartLot = 0.01;

input double summ=false; //true, открываем позиции в обе стороны

input int Slippage = 30; // установим значение проскальзывания



void OnTick()

{

if(summ) { // открываем однупозицию, покупка.

OrderSend(

Symbol(),

OP_BUY,

StartLot,

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,

0,

0,
