@saxena_puru @7AustinL @CliffordAsness @uber_trading After some testing, I'm using a variation to @saxena_puru  strategy in my IRA a/c where I don't use margin. By buying SH(first choice), SDS, SPXU which are 1x, 2x, 3x inverse SP500 inverse ETFs at trigger times. 
Not perfect but helped a little in March.
