老师:
我在转化如下通达信公式时,出现错误,想请老师指点原因,谢谢!
X_15 = HIGH - REF(HIGH, 1)
X_16 = REF(LOW, 1) - LOW
X_17 = SUM(IF(X_15 > 0 & X_15 > X_16, X_15, 0), 14)
出错提示:
X_17 = SUM(IF(X_15 > 0 & X_15 > X_16, X_15, 0), 14)
TypeError: ufunc 'bitwise_and' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
