tradeUpdate

tradeUpdate(TRADE*, int NewLots, var NewStop, var NewTP, int NewLifeTime)

Resizes or updates parameters of a particular open or pending trade.

tradeUpdatePool()

Updates pool trades to the current open virtual trades in virtual hedging mode. Automatically performed after any trade with Hedge = 4, or once per bar with Hedge = 5. Must be called by script with Hedge = 6.

Parameters:

TRADE*	Pointer to the trade to be updated, or 0 to update pool trades to the current open virtual trades.
NewLots	New number of lots, or 0 for not resizing. For reducing the trade size, partial closing must be supported by the broker; for increasing the trade size, virtual hedging must be enabled.
NewStop	New stop loss limit, or 0 for no change.
NewTP	New profit target, or 0 for no change.
NewLifeTime	New life time in number of bars, or 0 for no change.

Returns:

0 when the operation failed, otherwise nonzero.

Remarks:

Only the positions (NewLots) of real or virtual trades can be increased. Pool trades take over the new lot size either at the next bar or when calling tradeUpdate().
Trades are automatically updated with the new parameters when the maximum number of trades by MaxLong/MaxShort is exceeded.
If the TRAILSTOP or TRAILPROFIT flags are set, stops and profit targets are only changed when they are closer to the current price level.

Example:

function double_all_trades()
{
  if(Hedge < 4) return;
  for(open_trades) 
    if(TradeIsVirtual))
      tradeUpdate(ThisTrade,2*TradeLots,0,0,0);
  tradeUpdatePool(); // adapt pool trades
}
