$S&P 500 Index (.SPX.US)$ $Nasdaq Composite Index (.IXIC.US)$ $Dow Jones Industrial Average (.DJI.US)$ The mid-term trend of SPX has already turned bearish. How many short positions should be taken at this time?

$Tesla (TSLA.US)$ After Tesla reaches my system performance, I will determine 220-230, today is a good day for sell put, and I will do options of 170-200 for one week to one month.
