DGL Trade Bands are entry/exit “trade bands”. There are two bands for buying and two for selling. Buy 1 and Buy 2 bands are used to determine possible entry points. Sell 1 and Sell 2 bands are used to determine possible exit points. Once a trade is entered the DGL Trade Bands can also be used as stops.
