Rate of Change — the percentage price change over N periods.
The Rate of Change (ROC) computes the percentage change in price relative to the price n periods ago. Values above zero mean price momentum is directed upward, below zero — downward. The zero crossing is used as a trading signal; it is also applied in the KST and Coppock Curve.
ROC = (Close - Close[n]) / Close[n] * 100

Trigger Direction Condition Description Level cross up 🟢 Buy The indicator value crossed the specified level from below to above. The ROC line crosses the configurable Level from below to above. Level is set in the trigger parameters. Level cross down 🔴 Sell The indicator value crossed the specified level from above to below. The ROC line crosses the Level from above to below. Level is set in the trigger parameters. Value above level by N 🟢 Buy The indicator value rose above the level by the specified distance. The ROC line crosses the Level + Distance mark moving up. The distance delays entry until a confirmed breakout of the level. Value below level by N 🔴 Sell The indicator value dropped below the level by the specified distance. The ROC line crosses the Level − Distance mark moving down. Value rising 🟢 Buy The indicator value is rising relative to the previous bar. The ROC line is higher on the current bar than on the previous one — upward momentum. Value falling 🔴 Sell The indicator value is falling relative to the previous bar. The ROC line is lower on the current bar than on the previous one — downward momentum. Fires on every declining bar. Slope turns positive 🟢 Buy The indicator’s slope turned positive — an upward reversal. The ROC line changes its slope from falling to rising — the indicator stopped falling and started rising. Slope turns negative 🔴 Sell The indicator’s slope turned negative — a downward reversal. The ROC line changes its slope from rising to falling — the indicator stopped rising and started falling. Zero cross up 🟢 Buy The indicator line crossed zero from below to above — a buy signal. The ROC line crosses the zero level from below to above. Zero cross down 🔴 Sell The indicator line crossed zero from above to below — a sell signal. The ROC line crosses the zero level from above to below.
