I banked when my overnight short into the previous day's spike paid off. Tried re-shorting into a pop and ended up cutting my loss short when the stock didn't look like it would break support. Then, minutes later, it DID break support. Still happy I was disciplined enough to take a small loss. The gain would've been small as well. Whether I take a small gain or a small loss doesn't matter on the grand scale of growing my account exponentially.
