Automatic Order Placement - Timing and Threading Issues

[Automatic Order Placement - Timing and Threading Issues]

I'm not sure of your trading strategy but I think you refer to the "magic" "Trailing Stop Orders"

http://www.interactivebrokers.com/en/trading/orders/trailingStops.php

 

My broker is not IB I'm with TDW and ATraders + ToS platform to trade and don't use the API but if I can find some time I will learn JS... I've programmed in tha past and just konwing HTML and small amount of JavaScript give me an edge make tools that suit my needs.

 

Let me know if it was a VTSO or Trailing Stop Orders that you look for...

These aren't what I mean, but thanks for the message. I don't think that what I'm trying to exists as a conventional order/stop-loss type.

[Automatic Order Placement - Timing and Threading Issues]

Hello everyone,

 

I've had this account for a while and have been browsing the forums, but I believe that this is my first post. I'm using Interactive Brokers, and programming in Java, using the TWS Java API. The specifics probably don't matter, since I'm sure these issues arise no matter which platform/programming language is being used.

 

My question is this:

I haven't started trading with actual money yet, and have just been using their simulated trading (which is an excellent feature of IB btw) with good results. Part of my system involves changing a trailing stop loss on fairly short time intervals. When programming the change in stop loss there is a problem. In IB you can only 'update' a stop loss once. In my system I update it many many times while holding a position. So, I'm faced with two options: I can cancel the stop loss and then submit a new stop loss, or submit a new stop loss and then cancel the older one. If I cancel first, then there is a point in time (less than a second, but important in the long run) where I have no protection. Alternatively, I can have two stop orders active for a point in time, during which it is possible that both are triggered, and I end up a holding on the opposite side.

 

Have any of you found this to be a real problem? If so, how have you approached it?

 

Thanks,

Dayvan Cowboy
