Quote from Catoosa:
The bad thing about LIT orders is there must be a trade at the trigger price for the order to go active. Trading through the trigger price will not trigger the order. This has happened to me many times. I think IB should change the trigger method for LIT so the order will go active if the trade price trades at or through the trigger price (buy if the trade price drops down to < or = the trigger price and sell if the trade price goes up to > or= the trigger price). Because of this problem, I usually use the conditional orders to buy if the price drops down to what I want to pay or sell if the price goes up to the price at which I want to sell. The bad problem with using conditional orders is each order takes way to long to setup prior to entering the order.
This is not the case, trading thru the trigger price would also trigger the order. If you have any examples to the contrary, please open an issue with our tech support. Thanks!
