通达信价格标准差指标

㈠ 求 股票代码 DKDB 多空对比

短期:(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100,linethick2;
中期回:(CLOSE-LLV(LOW,10))/(HHV(HIGH,10)-LLV(LOW,10))*100,linethick2;
中长期答:(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100,linethick2;
长期:(CLOSE-LLV(LOW,30))/(HHV(HIGH,30)-LLV(LOW,30))*100,linethick2,COLORRED;

㈡ 请问在通达信指标中，“收盘价的5日估算标准差”如何写

N日估算标准差
STD(CLOSE,5);
