回调探底转强提示指标(源码)
这条指标把长期均线、34周期位置、随机值的谷底读数和MACD摆在一起，组合出9种文字提示：V型反转、底部拉升、探底回升、强势回调、通道回调、横盘转强、打压转升等，把回调与转强的位置直接标在K线上。
逻辑
长期均线由5、8、13这3层平滑再叠50周期构成，作为底部拉升的判定基准。
34周期位置读数由1以下上穿1时，判为中线由弱转强。
谷底读数用27周期随机值做3倍减2倍的平滑，它的3周期最低值和12日均线互相比较，用来锁定谷底与回调的起点。
跳空与洗盘另算一组条件：加权价的3层平滑线金叉、7周期涨跌比放大、144日均线与50日均线的比值收敛，分别对应底部拉升与回调这2类形态。
MACD与随机指标负责二次确认，快慢线的交叉方向决定提示落在低位还是高位。
文字提示共9类，按条件组合分别写在最高价上方或最低价下方，一眼能看出当下是哪一种状态。
参数微调
5、8、13、50是均线链的4段周期，改大均线更平缓。
27、12是谷底读数的取样与均值长度，改小提示更密。
34是中线位置的区间长度，改大对趋势的判定更慢。
