Well I managed to short at the bottom again.
BTC Nov 16 1685 call for $41, sold this morning at $8.20, waited to close long side STC 1640 for $6.75, bought 0.70.
This was a small portion of my position as I see price dropping precipitously. At least I learned not to sell all when pain is intense. Next, learn to pass when price moved dramatically, unless brave enough to go against trend and keep it small initially.
