The behaviour of these functions is affected by settings in php.ini.
| Name | Default | Changeable | Changelog |
|---|---|---|---|
| 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 |
Here's a short explanation of the configuration directives.
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.
