In reference to capturing price breakouts in liquid instruments, is there a set time in seconds anyone would suggest before canceling unfilled limit orders, to avoid toxic order flow? Non-HFT of course
You can't capture break out with passive/resting limit orders.capturing price breakouts
Sure you can. I do it on a daily basis. To clarify, I’m not talking resting bracket orders. Liquid markets back and fill constantly. Once price meets the criteria, you send the limit order to add/take liquidity, hopefully leaning into the positive order flow. I currently allow 30 seconds till cancel, but toxic order flow is the one thing I can’t quantify, so just trying to gather opinions.You can't capture break out with passive/resting limit orders.

With the prevalence of the HF players, providing liquidity exposes a non-HF trader to massive negative selection. It's obvious that in that environment (tighter spreads, higher potential for negative selection) it makes more sense to execute aggressively if you can't compete on latency.One interesting thing he said is that he no longer posts limit orders and just takes liquidity instead.
I think you’ve convinced me to agree with you. This isn’t child’s play.I don't think a general rule like cancelling after x seconds will work well. More likely you have to predict short term movements from order book data and this is in the realm of hft.
This sounds interesting. I’m inI can't remember which thread, but someone posted Dennis Dick's episode of Interview with Traders podcast. Very informative. One interesting thing he said is that he no longer posts limit orders
