Aroon

ایده به زبان ساده

In a strong uptrend new highs come often, so the last high is recent. Aroon Up is 100 when the high was today and falls as it gets older; Aroon Down does the same for lows.

روش محاسبه

Count how many candles ago the highest high (or lowest low) occurred within the period and convert it to a percentage.

Aroon Up = 100 × (N − candles since highest high) ÷ N
Aroon Down = 100 × (N − candles since lowest low) ÷ N   (N = 25)

نحوه استفاده

• Aroon Up above 70 and Down below 30: strong uptrend; the reverse: downtrend.
• Lines crossing: a possible trend change. Both low: consolidation.

نتیجه‌گیری

• Aroon measures time since extremes, not price distance, so it spots trend starts early.

مراقب این‌ها باشید

• Ranges produce frequent crossovers.
