The PriceZoneOscillatorLX strategy generates Long Exit signals when PZO values reach certain levels. Uptrend and non-trending market conditions are considered in this strategy. To check for trend existence, PriceZoneOscillator strategies use the Average Directional Index (ADX). If the ADX indicates trending conditions, an exponential moving average (EMA) is used for defining trend direction. By default, the strategy employs the 14 period ADX and the 60 period EMA.

In case the trend mode is spotted (ADX > 18), Long Exit signals are issued when:

  • PZO values rise above the "+60" level and start to go down afterwards, or

  • the price is below EMA (downtrend) and PZO is negative.

In non-trending conditions (ADX < 18), these signals are issued when:

  • having crossed the "+40" level from above, the PZO rises above the "+60" level and starts to go down, or

  • having crossed the "+40" level from above, the PZO falls below zero while the price is below the EMA, or

  • having crossed the "+15" level from below, the PZO fails to rise above "+40" and falls below "-5".
