Overbought & Oversold Oscillator - By CryptoEason
Обновлено
This is an overbought/oversold indicator that combines EMA / ATR / RSI and Bollinger Bands.
Overbought Definition:
When the RSI is greater than 70, and the price is above EMA20 + 2.5 * ATR.
When the price meets the overbought condition, the oscillator value will exceed 40, and a red bar will be displayed on the chart.
Oversold Definition:
When the RSI is less than 30, and the price is below EMA20 - 2.5 * ATR.
When the price meets the oversold condition, the oscillator value will drop below -40, and a green bar will be displayed on the chart.
The default average price used is EMA20, but you can modify it to SMA20 or adjust the length in the settings.
The default RSI length is set to 14, but this can also be customized. You can also adjust the ATR overbought/oversold multiplier in the settings, for example, setting it to 3.
Bollinger Bands:
The Bollinger Bands are used as a supplementary tool.
When the price is overbought and above the upper Bollinger Band, a red dot will be displayed.
When the price is oversold and below the lower Bollinger Band, a green dot will be displayed.
Buy and Sell Signals:
When the price moves from an overbought condition to a non-overbought condition, a sell signal is generated.
When the price moves from an oversold condition to a non-oversold condition, a buy signal is generated.
Altcoin Buy/Sell Signals:
In crypto markets, we usually view the bitcoin chart, so for the reason of convenience, I have also included altcoins buy and sell signals for 15 different altcoins. The default list includes: ETH / SOL / AVAX / DOT / APT / NEAR / ADA / SUI / MATIC / OP / PEPE / BLUR / GLMR / ASTR / APE.
You can customize these 15 altcoin pairs in the settings to any altcoins you prefer. When a buy or sell signal appears for one of these altcoins, you can quickly switch to its chart to view the signal. This is for convenience, so you don't need to check each chart's overbought/oversold status one by one; you only need to view the charts when a signal appears.
Reminder:
The overbought/oversold indicator works best in ranging markets. Use carefully when applying this indicator in a trending market. During trends, the price can keep remaining at overbought / oversold level.
Note:
If you think this indicator should have additional features that are currently not available, feel free to leave a comment and let me know.
=============== 中文說明（Chinese Introduction）===============
這是一個超買超賣指標，該指標結合了 EMA / ATR / RSI 與 Bollinger Bands。
我將超買定義為：
當RSI大於70，且價格大於 EMA20 + 2.5*ATR
當價格符合超買定義時，此時振盪器的值會大於40，並在圖表上顯示紅柱。
我將超賣定義為：
RSI < 30 且價格小於 EMA20 - 2.5 * ATR
當價格符合超賣定義時，此時振盪器的值為低於-40，並在圖表上顯示綠柱。
平均價格使用的是EMA20，但你可以在設定中修改成SMA20，或是其它長度。
預設RSI長度為14，你可以在設定中修改成其它參數。
你也可以在設定中將 ATR 超買超賣乘數改成其他倍數，例如3。
Bollinger Bands 在這個指標中的作用為輔助，當價格位於超買且在布林帶上邊界之外，會顯示紅點，當價格位於超賣且價格低於布林帶下邊界之外，會顯示綠點。
超指標還提供了買入與賣出信號：
當價格從超買狀態變為非超買狀態時，顯示賣出信號。
當價格從超賣狀態變為非超賣狀態時，顯示買入信號。
我還再這個指標上加入了山寨幣的買入賣出信號，一共十五組，預設為：
ETH / SOL / AVAX / DOT / APT /NEAR / ADA / SUI / MATIC / OP / PEPE / BLUR / GLMR / ASTR / APE
你可以客製化這十五組山寨幣的標的，在設定中修改成你喜歡的山寨幣。
當你在圖表上發現了某個山寨幣出現買入賣出信號，你可以迅速切換圖表到該山寨幣圖表上，提供這個山寨幣買入賣出信號，僅僅是為了方便性，讓你不用逐一檢查每個圖表的超買超賣狀態，僅在出現信號再查看即可。
提醒：
超買超賣指標比較適合用在震盪行情，當趨勢行情來臨時，需要謹慎使用這個超買超賣指標。
因為當趨勢來臨時，價格可以一直處在超買狀態或超賣狀態。
註：
如果你認為這個指標應該多增加什麼功能，但是目前沒有，歡迎留言告訴我。

Информация о релизе
In order to make this indicator more visual, I added three new features:1.Show EMA/MA lines on the main chart
2. Show ATR overbought and oversold upper and lower lines on the main chart
3. Highlight overbought and oversold Candles on the main chart
These three features are turned on by default. If you don't want to display them, you can turn them off in the settings.
========== 中文說明（Chinese Explanation）==========
為了讓這個指標更加可視化，我新增了三個功能：
1.可以在主圖表上顯示 EMA/MA 線
2.可以在主圖表上顯示 ATR 超買超賣上下邊界
3.可以在主圖表上高亮超買超賣K線
這三個功能預設是開啟的，如果你不想要顯示的話，可以在設定中關閉它們。
