Is someone using Tradestation? Do they have increased margin requirements for writing options on VXXB and UVXY? It'd be a great help if someone could check the margin requirements of 1 naked call for these two securities on the trading platform and tell the results! On their live chat I was told they aren't in the list for special margin requirements, but I'm a bit wary as it's the same thing at IB(they are not on the list), but when I put the order in TWS it shows the real initial margin (currently about 4k for 1 naked VXXB call and 8.8 for UVXY)
They just replied in an email: "We require 100% of underlying value for naked call/put writing" So it's 100% on Tradestation and Tastyworks vs (currently) 121%(VXXB) and 180%(UVXY) on IB
