Quote from bone:
As an official big mouth asshole with a Trading Technologies platform and a dedicated high speed line who has a live ES order book up at all times, let me burst your SIM bubble: 1. They all go at once in the ES order book. You will never get the chance to be a "fellow consumer" at that price. 2. There are all kinds of 'footprint' emulating algorithms already in place that would never get even remotely close to your simulated performance. Yep, I personally know of trading groups who try to piggyback onto liquidity takers versus liquidity providers. Very sophisticated algos that try to segregate and piggyback aggressors who are hitting bids and lifting offers. 3. Hint: Not all of these "consumers" are even remotely correct in terms of bias and follow-through to the next price. As a matter of fact, competing algos will iceberg orders into them and give them all they want at that price point. 4. If it looks too good to be true, it surely is. I know HFT groups who pay $60K per month for dedicated lines and infrastructure, they are located WITHIN the freaking CME building, and they still get picked off with Globex products. One of the problems with SIM is that execution and latency dependent strategies are never properly tested - and make no mistake, a strategy that segregates and filters order flow most certainly is.
