## Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Trader Configure Options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
trader.real_precision | 3 | `INI_ALL` | Since trader 0.2.1
trader.real_round_mode | HALF_DOWN | `INI_ALL` | Since trader 0.3.0

Here's a short explanation of the configuration directives.

`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.
