Error - Stop price can't be changed below the market

I have an ATM I'm testing that does auto trail, and sometimes when I order and it triggers, I get an error like this:



Why is this popping up randomly on some orders?
I don't think it's breaking or interrupting the order, but it is intrusive and annoying. Is there any way to disable this?

You need to make sure there is enough room to place your order in relation to the current price.

I use this in one of my script:

case 2: // BO H[1] or BO L[1] /buy if price crosses previous bar high/-/Sell if price crosses previous bar low
                        
 //-
 if (buyModeEnabled) /// If Buy button is turned ON
 {
  if (GetCurrentAsk() <= High[1] + stopLimitMargin * TickSize)
  {
   tradeDir = 1;
  }
 }

 if (sellModeEnabled) /// If Sell button is turned ON
 {
  if (GetCurrentBid() >= Low[1] - stopLimitMargin * TickSize)
  {
   tradeDir = 2;
  }
 }​

Hello MatthewLesko,

The rejection error indicates the buy stop market order was modified to a price that was below the current market price. After the modification triggered, the market went up. When the order modification arrived at the "exchange" (simulator fill engine), the order price was below the current market price. To reduce the chance of getting this order rejection, please modify the stop market order further away from the market price.
