Before commissions and exchange fees. Prices round to the nearest tick of ¼/32. Enter prices in points and 32nds, e.g. 110'16.5 or 110-165 (= 110 + 16.5/32), or as decimals.
One tick is 1/4 of 1/32 of a point, worth $7.8125 per contract. A full point is worth $1,000.
In points and 32nds of a point, e.g. 108'16.25 = 108 + 16.25/32. Platforms often write fractions as a third digit (108-162).
The COT Index places a group's current net position within its own range over a lookback window: 100 = the most net long in that window, 0 = the most net short. It measures positioning extremes, not timing.
