Three-Parameter RSI with Overbought/Oversold Zones
(Parameters and overbought/oversold zones can be adjusted independently; each cycle line can be turned on or off separately), facilitating the observation of multi-cycle resonance:

• Trend Consistency:
The short-, medium-, and long-cycle RSI move in the same direction. If the short-cycle RSI stays above the medium- and long-cycle RSI, it indicates a bullish trend; otherwise, it indicates a bearish trend.

• Divergence and Reversal:
When the price hits a new high/low but the short-cycle RSI fails to follow suit, and the medium- and long-cycle RSI weakens/recovers, it signals a potential pullback/rally.

• Overbought/Oversold Confirmation:
When a single-cycle RSI enters the overbought or oversold zone, judgment should be combined with other cycles; if multiple cycles enter the overbought or oversold zone simultaneously, the signal is more reliable.

• Cycle Resonance:
When multiple-cycle RSI send the same signal (e.g., all breaking through the 50 midline), the probability of the trend continuing or reversing is higher, which can assist in decision-making.

带超买超卖区域的三参数 RSI

（可自主调整参数与超买超卖区域，支持单独开关各周期线），便于观察多周期共振：

•趋势一致性：

短、中、长周期 RSI 同向运行，短周期在中长周期上方为多头趋势；反之则为空头趋势。

•背离与反转：

价格创新高 / 低但短周期 RSI 未同步，且中长周期 RSI 走弱 / 回升，提示可能回调 / 反弹。

•超买超卖确认：

单周期超买超卖时，需结合其他周期判断；多周期同时超买超卖，信号更可靠。

•周期共振：

多周期 RSI 同发信号（如均突破 50 中轴线），趋势延续或反转的概率更高，可辅助决策。
