Result of MACD when signalperiod = 1?

[ojipadeson]

When setting signalperiod = 1 in function MACD, the last two results of the bar value is not in a stable condition, and always approaching 0. How the function calculates when signalperiod = 1? Why the function can accept signalperiod = 1?

You could look through the source code:

https://github.com/TA-Lib/ta-lib/blob/master/src/ta_func/ta_MACD.c

I don’t believe that’s a valid parameter value, though. But don’t have time to investigate right now.

signalperiod = 1 appears to be a valid value according to the code that I found in input validation part of the code...below. I guess I have a similar question, when you have some time, as to why this is a valid input and the meaning of the functions output.

many thanks
