Attach sell order at higher price in order book

[batssmasher]

Ok i was able to get the limit order to work . the strat now issue limit order 2% above the current low sell order as soon as it buy
But now i dont know how to cancel that limit order and create a sticky order once i reach the 1% ( using the slow strat )

i tried with trader.js but couldnot find how to do that
