Informations about the package php-trader-native
PHP Trader Native
This is a PHP port of the Trader extension for PHP, which is a port of the TA-LIB C/Java code.
This port is written in PHP and without any other requirements.
The goal is that this library can be used by those whom cannot install the PHP Trader extension.
- PHP >= 7.0.0
That's the only thing you need! As stated, you do not need to install any extensions for this library.
This library is intended to be installed with composer.
composer require lupecode/php-trader-native
This library is intended to be a drop-in replacement for the Trader extension, with a minimum of code changed.
If you had
trader_adosc($high, $low, $close, $volume, $fastPeriod, $slowPeriod)
You can swap that with
Trader::adosc($high, $low, $close, $volume, $fastPeriod, $slowPeriod)
You only need to change
Trader::. That's it!
Another option that this package provides is to use functions that have an easier to understand name.
If you do not to use
adosc because it is not descriptive enough, you can instead use
chaikinAccumulationDistributionOscillator like this:
TraderFriendly::chaikinAccumulationDistributionOscillator($high, $low, $close, $volume, $fastPeriod, $slowPeriod)
Note about default values
The PECL version of the TA-LIB, "Trader", does not have the correct default values for the functions.
A quick look shows that many of the function use the minimum value for the optional parameters instead of the defaults used in the C/Java version of TA-LIB.
Some of the tests, like
testAdOscDefaultsDifferent pass as long as the PECL Trader library uses different defaults than those in the C/Java code.
This package uses the C/Java defaults and not the PECL defaults.
Given that this library is written in pure PHP, is does run slower than the PECL extension which is written in C. My benchmarks give 5x to 30x slower depending on the function.
I welcome any help with optimizations! I have not worked to optimize this library; it's a simple conversion from C to PHP.
- PHP >= 7.0.0
- ext_trader >= 0.4.1 here
Checkout the repository and then install with composer.
git checkout [email protected]:LupeCode/phpTraderNative.git cd phpTraderNative composer install --dev
Two PHPUnit XML files are included, one for testing and the other for coverage. This is due to the fact that when some tests are run with coverage, PHP hangs and never finishes.
Run the tests using
php -dxdebug.coverage_enable=0 ./vendor/phpunit/phpunit/phpunit --configuration ./phpunit.xml ./tests
Run the coverage using
php -dxdebug.coverage_enable=1 ./vendor/phpunit/phpunit/phpunit --configuration ./phpunit_coverage.xml ./tests
