Does anyone know how to program a non-display limit order or Iceberg order in Tradestation Easylanguage?
After studying the TS easy language and its functions for a few months, my suggestion, the best thing to do is to give up on it, and transfer all your funds to some other brokers that actually have a tech team to develope and support their APIs.
Yes, we use IBKR for years. Just that IBKR API trading does not offer free commissions, and we have large enough volume to make it reasonable to consider commission cost. That was the main reason to try TS, but it turned out a total waste of time.
