Aroon upper and lower "over-bought" and "over-sold" lines. The upper is set at 10. The lower is automatically adjusted as negative of the upper (-10). The upper is adjustable by the user.
When Switch is set at "0" the signals are:
If the current Aroon Average Close is less than the Upper line, and the previous Aroon Average Close is greater than or equal to the Upper line, BUY.
If the current Aroon Average Close is greater than the Lower line, and the previous Aroon Average Close is less than or equal to the Upper line, SELL.
If Switch is set to "1" the BUY and the SELL trade places in the above.
Creation of BUYs and SELLs is controlled to some extent by "Approx Max # Pos Open" and "Martingale Multiplier" and "Amount(Lots)."
