Option1: Rewriting the entire EA into Zorro/C would be ideal but not financially feasible. The EA uses a breakout system and broker latency/slippage sensitive.

Option2: With MT4 via Zorro S Bridge would the EA be able to run on MT4, with just the lot sizing having to be re-written in the EA? Does this approach increase the order execution speed on Oanda side? From what I udnerstand it would go MT4 > Zorro S Bridge > Oanda/API?

Thanks
