- // Elder Triple Screen Trading System. As derrived from "Trading For A Living"
- // and "Come Into My Trading Room" by Alexander Elder. This scan finds long
- // candidates by the weekly MACD rising and the weekly 13 period Force Index
- // above it's zero line. Plot a weekly EMA (26 period)...it should be rising
- // to go long. The daily 2 period Force Index must be below it's zero line.
- // Look for the stock on a pullback around it's daily 13 period ema. Also use
- // the daily 22 period ema to determine the direction of the daily trend. Do
- // the opposite for shorts. Best used as an Exploration.
