//1. Remember F, AO, AC and Zone Add Ons signals and hits
//2. Integrate squat bars with exit signals somehow.

//in other words, the market only moves when there is Chaos present.

//   we double the number of lower low (higher high) bars needed.
//4. Base Bar is the Lowest High (Highest Low) in buy (sell). Signal Bar is the bar before the base bar.
//5. Buy (Sell) stop is defined as the High (Low) + 1 tick of the Signal Bar.
//6. As long as the Signal bar itself is above the Balance Line, we act as if the entire formation were above the Balance Line.
//7. The buy (sell) stop stays in place unless
//      (a) it is triggered
//      OR
//      (b) another bar with a lower High (Higher Low) is formed, creating a different base bar.
//8. You do not sell above the Alligator's mouth and you do not buy below the Alligator's mouth.
