Brief Note Regarding GLL

FYI, gold is down about 0.7% in the pre-market, so the GLL ETF would gap up about 1.5% since it is a 2x inverse ETF. So you could keep an eye on if this changes before the market open to calculate position size. But I would use 15.75 as the approximate opening price at this time. The stop will still be 14.25. So the risk per share is $1.50.

The conventional wisdom on position sizing is to risk 2% of trading account or less per trade. There is a precise way to calculate exactly how much to risk, but one has to know win rates and average winner vs loser stats to do that.
