These MM options (% of...) are maybe not useful in every situation. If it is "% of Balance" and the value is 100(%) and Balance is 10000 and the market is EURUSD when 1 lot is 100000, then the lot size will be 0.1.
I think this indicator is loaded, but can't be read or something like that. Is it working otherwise, if you use it manually? Or within another EA somewhere from internet? And after these error messages, will it eventually start to work or they have no end?
How about input parameters, are they ok? - the same parameters count and order, the same datatypes or at least compatible datatypes?
