General errors
If there is an error in writing the CustomEMA formula in the MoonBot terminal on the Filters / Base tab of the strategy settings, for example, incorrect encoding, then the entry in the filters on the chart will be displayed as follows:
EMA Filters: CustomEMA: Not a EMA ()
To correct the error, carefully rewrite the entire formula in the CustomEMA parameter strictly in the English layout and follow the encoding of the text.
