EMA Error

[MixMe]

Hi, thank for cool extension, any Idea about this error?

[MixMe]

same problem with RSI:

this error appears after updating from v1 to v2

[jb-lopez]

Thanks for reporting the error @MixMe

Could you provide the input you were using that gave the error? My testing data doesn't generate any so it must not be comprehensive enough.

@MixMe what version of PHP are you using? static:$unstablePeriod should have 23 entries, but yours has two. My first thought is that the switch to using enums is to blame here, but it should work as long as you are using PHP 8.1+.

phpTraderNative/source/TALib/Core/Core.php

Line 99 in f6d8387

static::$unstablePeriod = \array_pad([], count(UnstablePeriodFunctionID::cases()) - 2, 0);

This is where the array is populated. v2 is using enumerations.

[MixMe]

I use PHP Version 8.2.10

[MixMe]

UnstablePeriodFunctionID::cases() return empty array

[jb-lopez]

Oh. How odd that it is working for me, but I can investigate that later.

That fix is easy enough. If you would like credit for it go ahead and make a pull request. If not I can make the change.

[MixMe]

Yes i can do it

[MixMe]

Hi @jb-lopez , how can I upload my changes?
