运行时配置

这些函数的行为受 php.ini 中的设置影响。

**Trader 配置选项**
名字	默认	可修改范围	更新日志
trader.real_precision	3	PHP_INI_ALL	Since trader 0.2.1
trader.real_round_mode	HALF_DOWN	PHP_INI_ALL	Since trader 0.3.0

这是配置指令的简短说明。

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.
