Spice Trend will act as a resistance and support trend line. If price action ignites, and or cross the trend, you can assume that the price action is ready to reverse. In this case, orange reversal bars printed, and price action was primed to reverse. So you can make the decision to enter in on the printed orange bar, or enter in on the buy signal. Eventually, price action crosses over Spice Trend, and you can decide to take profit on the position.
