Hello,
I have extensive experience in TradeStation, MultiCharts, Ninja Trader programming and trading US markets (stocks, futures, options). Selection of the optimal software platform depends on your broker. Multicharts f. e. supports many brokers, and will be a good solution.
I can convert Thinkorswim code to MultiCharts. The program will analyze bid/ask prices in several strikes and trade the best option in the chain.
Regards,
Alexander
