trader.real_precision integer

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.
