I have made spread monitoring software that can currently attach to MT4&5 clients and log historical spread data to outer software. So far i have monitoring and recording of lowest, avg and peak spreads for each instrument during low timespans and rerouting orders between brokers depending on lowest costs obtained trough monte carlo simulation with past trade data. Alternatively what other software is available that does the job of optimizing costs between brokers decently and would also allow communication to automated software outside of MT4/5 terminals or maybe even also compatable to NT and IBapi, other markets outside forex? Lets say there is commercial product in 1-2 month ,and it would require to make 2-3 or more accounts(depending on instruments you trade) with various brokers to use the routing software , would you be interested in paying something for it, if so how much?
I see various brokers offering their best spreads on specific instruments. If lots of positions throughout years it is useful for cost optimization. For long term positions where spread is low portion of the cost it may be useless extra complexity.
