ROC: Rate of Change
How much the price has changed in per cent compared with N candles ago.
用通俗的话解释
ROC is momentum in its simplest form: the percentage move over a fixed look-back. Above zero the price is higher than it was, below zero lower.
计算方法
Divide the change since N candles ago by the price N candles ago and multiply by 100.
ROC = (close − close[N]) ÷ close[N] × 100如何使用
- Crossing zero: momentum turns positive or negative.
- Divergence: price makes a new high while ROC does not.
得出结论
- Extreme readings compared with the ticker's own history often come before pauses.
示例
AAPL daily, ROC(12) = +8%: the price is 8% above where it was 12 sessions ago.
示例中的价格仅作说明。
注意事项
- One unusual candle N candles ago makes ROC jump when it drops out of the window.
一点历史
One of the oldest momentum measures, used by stock traders well before computers.
