It is my understanding that the micros and minis are near perfectly correlated and I'm guessing there are high frequency arbitrage traders that maintain that correlation.
So if I have a thus far successful emicro day trading strategy I can flip the switch to the mini. As opposed to increasing the qty on my micro orders and suffering the increased slippages and commissions?
P.S.
I've never made a manual trade in my life, honestly, I'm not even sure which buttons to press in interactive brokers. I'm a non-software engineer, who has learned to program and has dabbled with algorithmic trading for the last 3 years. So my apologies if this is an uninformed question.
The obvious approach would be to back test and find out, however, my most profitable strategy, cannot be back tested for a complicated set of reasons. Mostly, part of my strategy takes advantage of an idiosyncratic behavior of the IBKR API, that I accidentally noticed correlates with a market condition. Has to do with how IBKR responds to messages, how long and in which order. I can't replicate that.
It also does not help that interactive brokers does not have a back testing module.
It is a scalping strategy, that can survive high latency 300ms. The reason I chose the e micro to develop the strategy was to reduce the "tuition". Otherwise, I'd have to paper trade for years to really feel comfortable going live.
So I paper traded for 2 months, and I've been live for 3 months the results matched. Since I do not have years of back test available, I've been slowly scaling up. Since I am approaching 10 microcontracts, it makes logical sense to look to the emini.
Perhaps my approach will be too paper trade for a week or two, to confirm that it works for Emini. Can anyone confirm that they are near perfectly correlated?
