Moving a stoploss after strategy created it

Desktop SDK - Strategies
1

My strategy takes a trade and places a stoploss order. If I change the stoploss order then the whole position gets cancelled by ninjatrader. In playback mode it’s no problem to do that. This is how I place the order:

if (_stopPriceLong < GetCurrentBid())
{
_stopLong = ExitLongStopMarket(0,true,_longFilled,_stopPriceLo ng,“LongStop”,"LongEntry "+StrategyIdentifier);

}
Eventhough LiveUntilCancel is set to true I can’t move the order on the chart manually.

Question 1: How can I move the stoploss order once it was placed by the strategy?
Question 2: Why does it work in Playback but not in Sim/Live trading?

​​​​​​​Thank you!
