I trade in Tradestation and I'd like to learn more about reducing slippage as my account size and trading volume grows. I'm trying to understand the best methods and advanced order types for reducing market impact. Are there books, videos, other websites anyone would recommend? For example, if I want to trade 100 lot, is there a way to work this in Tradestation to trade 20 lots every 5 seconds at market? Or with limit orders is there a way to work 10 at the limit price, and then once those get executed, this would trigger the remaining orders at market? Thanks for any recommendations!
