Hi ET! I want to submit an order to short @ the ask unless the ask drops below 1% of the close? Is there an order type in IB TWS, another interface (NinjaTrader, etc), or even a clunky roundabout way of accomplishing this? Thanks for your help! Example: Stock X closes regular session @ $43 last sale price. Bid is at $42.90 / ask $43. I submit an order to short @ $43, and my order will chase the best ask so long as it does not dip below $42.57 (1% below day's closing price) at which point it will either cancel my order or keep it set at the $42.57 ask.
