Main Algotrading documentation Trade operations Positions

Positions.Close

We send a request to close an existing open position.

int err = Positions.Close(int PositionId, int Volume, bool isAsync=false);

Input parameters

Parameters
Type
Description
positionId
int
Position identifier positionId
Volume
double
Position volume we want to close in lots
isAsync
bool
Asynchronous mode (enabled or disabled).
Disabled by default


Return value

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

0
Position is successfully closed
If an error occurs, it returns the server error code


If isAsync = true (asynchronous mode)

0
The request to close the position was successfully sent to the server. It does not mean that the position has already been closed or will definitely be closed.
If an error occurs, it returns the error code received on the client. The codes match the server error codes.


Example:

//------------------------------------
// Close all positions on the account
//------------------------------------
private void CloseAllPos()
{
string line = "";
int err = 0;
line = line + "Positions Count = " + GetPositionCount().ToString() + Environment.NewLine;
if (GetPositionCount() > 0) {
for (var i = Positions.Count - 1; i >= 0; i--) {
Position pos = Positions.Find(Positions[i].PositionId);
if (pos != null) {
err = Positions.Close(pos.PositionId, pos.Volume);
if (err == 0) {
line = DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss:fff") + " Closed Success, PositionId = " + pos.PositionId.ToString() + " CurrentProfit:" + pos.Profit.ToString() + Environment.NewLine;
Print(mCommonLog, line);
} else {
line = DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss:fff") + " Closed Failed, ServerErrorCode = " + err.ToString() + Environment.NewLine;
Print(mCommonLog, line);
}
}
}
} else {
line = DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss:fff") + " Positions not found! ";
Print(mCommonLog, line);
}
}
//-------------------------------------------
// Count the number of open positions
//-------------------------------------------
private int GetPositionCount()
{
int poc = 0;
for (var i = Positions.Count - 1; i >= 0; i--) {
Position pos = Positions.Find(Positions[i].PositionId);
if (pos != null) {
if ((pos.PositionType == (int)PositionType.Buy || pos.PositionType == (int)PositionType.Sell)) {
poc++;
}
}
}
return(poc);
}
