Regarding the issue of setting the MT5 environment status - trading variety attributes

[Zhao Yang Wang]

Hi, everyone

Recently working on EA development, I found that the trading variety attributes of MT5 are:

Symbol_ VOLUME_ Limit is 0.5,

Symbol_ VOLUME_ MAX is 100.

May I ask, can these two variables be set by oneself? Or is it that the dealer has set it up and the user cannot modify it.

Thank you

It is defined by the broker in the Contract Specifications for each symbol.
