Asynchronously move SL and TP or close trades

Hi there,

For my own trading, I layer/build/scale in with very small, but many trades to build an overall position, and then move stops to secure trades.  At the moment I can only workout how to iterate over these trades 1 at a time, and execute the move one position at a time', something like:


 

      private void MoveStopLosses(IEnumerable<Position> positions, double newPrice)
       {
           Debug("Entered move stoploss");
           foreach (var position in positions)
           {
               position.ModifyStopLossPrice(newPrice);
           }
        }

This some times takes several seconds across a batch of 20 or50 postions, by which stage the advantage is gone and a healthy win becomes a loss.

Is there something conceptually like:

 

        private void MoveStopLosses(IEnumerable<Position> positions, double newPrice)
        {
            Debug("Entered move stoploss");
            foreach (var position in positions)
            {
                position.AsyncModifyStopLossPrice(newPrice);

            }

        }

Or, spawning a way to spawn a thread of each modification so the queue of modifications isn't so deep and serial in nature.   Or perhaps  a way to submit a batch to the server ? or some thing else to acheive the same end?

Thanks
