*BD* = As long as it is more than 1.618 we are fine but we prefer it to be 1.618 to 2.618. This is not much that important.
*AB* = CD pattern is usually extended. We shall talk about this in the example.
*XD* = 0.886. Slight deviation is OK.
*AC* = Range between 0.382 and 0.886
We buy at .886.
1. Never trade Bat unless its complete.
2. Never buy unless the D leg is complete i.e You see 1.618 on BD
3. Make the trade box seeing XD = .886
