抄底是一種炒股技巧，指在股價跌到低點時買入，期待后續上漲。抄底通常需要結合多種指標和條件來判斷。
?
這段代碼的具體思路是利用KDJ指標和其他條件來尋找抄底時機，并在圖表上繪制相應的提示符號。操作建議是在滿足以下條件時買入：
?
今日收盤價比25日前收盤價下跌超過13%
J線上穿J線的2日移動平均值且今日收盤價高于開盤價
昨日最高價減去開盤價與收盤價之比小于2%
前天和昨天收盤價低于開盤價
今日最高價高于昨日最高價且今日最高價減去收盤價與收盤價之比小于2%
昨日開盤價減去收盤價與今日收盤價之比大于1%
前天開盤價減去收盤價與今日收盤價之比小于9%

{關注盤后預警XG，預警XG完畢后，單獨列出一版塊，第二天可以把可以買入預警XG預警設置在這個版塊里，可以提高預警時間}
