Is it possible for someone to make money selling conversions / reversals using a retail platform such as IB? I don't see how such a strategy could work for something such as SPY where option spreads are tight, but it looks like there might be some opportunity for trading conversions / reversals on less-liquid stocks or ETFs with weekly options where the bid / ask spreads are wider. On the other hand, given that the opportunity is nearly-risk-free, it seems too good to be true and impossible to compete with large banks / HFT. Obviously, one would need to have low commissions and a broker which treats options assignment / exercise the same as trading a stock. Does anyone on here do this for a consistent, small, but almost risk-free arbitrage profit?
