I am evaluating a couple of options to monetize my trading system while I trade it live - one of these options being to offer a signal-service through Collective2. My system runs in NinjaTrader, Ninja only offers to send MKT orders to C2 (after an order is filled in an account mirrored in C2) - this will have so-much delay & associated slippage that it isn't a viable option IMO. Then there are a couple of utilities to replicate orders from TWS to C2 (IB2C2 & HPB), that seems a better option, but I can foresee an ocean of trouble (if not for me, for subscribers) when my system gets a "lucky" fill (price hit the LMT but didn't trade through), as it will generate exit orders while subscribers might not have any matching position. I am also wondering if, plain & simple, C2 can be used for day-trading systems (entry-signal to entry usually a good number of seconds - 10+, but sometimes as little as 1 or 2 sec). What is C2 reliability level? Bugs or error in relay of signals, servers outages, etc. Last but not least, what's your experience w/ subscriptions ? Time to 1st subscriber, time to 10 subscribers, subscriber churn, etc. Thanks in advance & happy new-year! PS- Are there alternatives to C2 for futures trading systems ?
