I did some testing of Tradier. I am on the Pro trial plan (10$/month after trial), which gives "0 commissions of options trading".
Two disclaimers: 0 commissions is not applied to index options (SPX, VIX, XSP, NDX, etc)
and there is still "transactional fees and additional fees" for each trade.
As SPY options are covered by 0 commissions I decided to test if this is makes sense to trade 10 SPY options vs 1 SPX option.
So here is final calculations:
to open and to close 10 SPY options I paid $1.55 in transactional fees and additional fees
to open and to close 1 SPX option I paid $1.75 in commissions + transactional fees and additional fees
so while there is a little benefit of trading SPY options, I am not sure dealing in 10x size
and favorable tax treatment for SPX worth the hassle to trade in SPY.
