The manual says otherwise:
If the TMF is passed to an enter command, it can receive up to 8 additional var parameters following the function name: enterLong(MyTMF, parameter1, parameter2...). They must also appear in the function's parameter list and keep their values during the lifetime of the trade. The global manage function has no parameters.
Also, 2-minute difference is 0.00138888. If there is any rounding involved internally, downcasting a var to a float, this shouldn't cause difference up in the 3-rd significant digit.
