Your max profit would've been if you closed both the call and put when the stock is at the strike, since that's where total position delta = 0 and that's where your straddle forms its peak
PTON was flying high after ZM earnings release, hoping for a similar spike in covid related sales, and a similar boost to it's stock price. I had sold a few ATM puts in PTON around 85. Bought them back when ZM and other tech shares crashed. PTON didn't fall much that day.
