這是配置指令的簡短說明。
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.
