Bitfinex PHP Library

This repo is the outcome of me ignoring the 2016 superbowl. Instead I streamed this for an hour and half on youtube (https://www.youtube.com/watch?v=rky1EnDqmhI). In the end we had a mini PHP library for the bitfinex API and a very simple trading bot. The bot uses bitcoinaverage.com API to determine if it is a "good" time to buy or sell.

Usage

Requirements

Bitfinex account with funds in appropriate finex wallets (exchange, trading)
Bitfinex API Keys and secret key
A server that is able to run PHP files.
(Optional) Access to Cronjobs (this way you can automate trading)

Download or clone the main project and extract files.

example.php will make trades if you run it. DELETE EVERYTHING AFTER require_once(config.php); if you don't want the bot to execute a trade. If you want the bot to run automatically, you will need to set up the example.php file to run as a cron job every N minutes/hours/days etc.

Update the config.php file with your api keys

 $api_key = "your_api_key";
 $api_secret = "your_api_secret";

How to do a market buy order on the exchange market

 $trade = new bitfinex($api_key, $api_secret);
 $buy = $trade->new_order("BTCUSD", "0.01", "1", "buy", "exchange market");

How to do a limit sell order on the margin market

 $trade = new bitfinex($api_key, $api_secret);
 $buy = $trade->new_order("BTCUSD", "0.01", "380.29", "sell", "limit");

Additional Info

The basic schematic is:

	$variable = new bitfinex($api_key, $api_secret);
	$variable2 = $variable->new_order("SYMBOL", "AMOUNT", "PRICE", "SIDE", "TYPE");

When making a limit order the price is the price you are looking to get met. When making a market order the price can be any random number. The SIDE refers to buy or sell. The TYPE is the type of order. If you want to do margin trades, enter the type without exchange in the front.

Example (exchange buy): ("BTCUSD", "0.01", "1", "buy", "exchange market");

Example (margin buy): ("BTCUSD", "0.01", "1", "buy", "market");

Cancelling Orders

	$order_id = "943715";
	$execute = $trade->cancel_order($order_id);

Cancel All Orders

	$execute = $trade->cancel_all();

Account Info

	$execute = $trade->account_info();
	print_r($execute);
	/*
    example response
    [{
    "maker_fees":"0.1",
    "taker_fees":"0.2",
	"fees":[{
	"pairs":"BTC",
	"maker_fees":"0.1",
	"taker_fees":"0.2"
    },{
	"pairs":"LTC",
	"maker_fees":"0.1",
	"taker_fees":"0.2"
    },
    {
	"pairs":"DRK",
	"maker_fees":"0.1",
	"taker_fees":"0.2"
	}]
    }]
    */

Deposit

	$method = "bitcoin";
	$wallet = "trading";
	$renew = 1;
	$execute = $trade->deposit($method, $wallet, $renew);

Deposit generates a BTC address to deposit funds into bitfinex $renew will generate a new fresh deposit address if set to 1, default is 0.

	/*
	example response
	{
	  "result":"success",
	  "method":"bitcoin",
	  "currency":"BTC",
