`trader.real_precision` `int`

- All the values in the returned arrays will be rounded to this precision. However the calculations inside TA-Lib happen with unrounded values.

`trader.real_round_mode` `string`

- Controls the trader real rounding policy. Valid values are `HALF_UP`, `HALF_DOWN`, `HALF_EVEN` and `HALF_ODD`. The behaviour is identical to the round() function used with the mode argument.
