Remarks
The MRO function is specifically designed to identify when a certain condition occurred. It checks from the current bar and works away from it.
The function returns a number representing how many bars ago the true/false expression was fulfilled (0 = current bar, 1 = one bar ago, 2 = 2 bars ago …). If the function does not find a bar within the specified Length, which meets the criteria, it will return a -1.
When using the MRO function in an analysis technique, always check the result of the MRO function before using the value in another calculation or function. If Test is not true within Length number of bars, a -1 value will be returned.
Example
Value1 = MRO(Close>Open, 5, 1);
