User interface is easy. Everything else not so much. Recently bought puts as downside protection. RH system linked it with another put (purchased on different day & different experation) as a calendar spread. Instead of executing the put (as I wanted the stock) they forced me to buy the put back around $5.50 ($550) when the stock was only about $2 OTM with about an hour to go in the session. Ask/bid spread was between 2.20 & 5.80, they did what they wanted to pocket $, not what I instructed.
