Main Algotrading documentation Trade operations Positions

Positions.Modify

We send a request to change an open position.

There are two options for calling a method:

int Positions.Modify(positionId, takeProfit, stopLoss, isJustCheck = false, isAsync = false)

Input parameters:

Parameters
Type
Description
positionId
int
Position unique identifier
takeProfit
double
Take profit. Price level in quoted currency for profit fixing.
 
stopLoss
double
Stop Loss. Price level in quoted currency for fixing losses.
isJustCheck
bool
Check mode (enabled or disabled). When the mode is enabled, a request to open a position is not sent, but only the possibility of opening with such parameters is checked. Disabled by default
 = false
isAsync
bool
Asynchronous mode (enabled or disabled).
Disabled by default
= false


int Positions.Modify(ref position, isJustCheck = false, isAsync = false)

Input parameters:

Parameters
Type
Description
position
An object that contains all the parameters of the operation to change the position
isJustCheck
bool
Check mode (enabled or disabled). When the mode is enabled, a request to open a position is not sent, but only the possibility of opening with such parameters is checked. Disabled by default
 = false
isAsync
bool
Asynchronous mode (enabled or disabled).
Disabled by default
= false


Return value

If isJustCheck = true, it returns the result code of the operation:

0
Check for the possibility of opening was successful. Check occurs on the client side
-1
Check failed


If isAsync = false (synchronous mode by default), it returns the result code of the operation:

0
Position has been successfully modified 
If an error occurs, it returns the server error code


If isAsync = true (asynchronous mode)

0
Position has been successfully modified 
If an error occurs, it returns the server error code


Example:

//-----------------------------------------------------------
// We modify stoploss and takeprofit of the position
//-----------------------------------------------------------
private void ModifyPosition(int positionId)
{
string line = "ModifyPosition: " + DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss:fff");

Position pos = Positions.Find(positionId);

if (pos != null) {
double takeProfit = Math.Round(pos.OpenPrice + 4000 / Math.Pow(10, Symbol.Digits), Symbol.Digits);
double stopLoss = Math.Round(pos.OpenPrice - 4000 / Math.Pow(10, Symbol.Digits), Symbol.Digits);

int err = Positions.Modify(pos.PositionId, takeProfit, stopLoss);

if (err == 0) {
line = line + Environment.NewLine +
" Symbol = " + Symbol.SymbolName + Environment.NewLine +
" Commission = " + pos.Commission.ToString() + Environment.NewLine +
" Margin = " + pos.Margin.ToString() + Environment.NewLine +
" OpenDate = " + pos.OpenDate.ToString("dd.MM.yyyy HH:mm:ss:fff") + Environment.NewLine +
" OpenPrice = " + pos.OpenPrice.ToString() + Environment.NewLine +
" Label = " + pos.Label + Environment.NewLine +
" TakeProfit = " + takeProfit.ToString() + Environment.NewLine +
" StopLoss = " + stopLoss.ToString() + Environment.NewLine +
" Swap = " + pos.Swap.ToString() + Environment.NewLine +
" PositionId = " + pos.PositionId.ToString() + Environment.NewLine +
" PositionType = " + pos.PositionType.ToString() + Environment.NewLine +
" Profit = " + pos.Profit.ToString() + Environment.NewLine;
} else {
line = line + " Failed, ServerErrorCode = " + err.ToString() + Environment.NewLine;
}
} else {
line = line + " Position not found " + Environment.NewLine;
}

using (StreamWriter sw = new StreamWriter(mOnTickLog, true))
sw.WriteLine(line);
