PHP example code for order placement through API

Alpaca Integration Applications
1

Hello

Is it possible to update the documentation to show example PHP code to interact with the API in order to place orders?

Has anyone maybe coded this already ?

Would really help me out if you can share / update this.

This is the page: https://alpaca.markets/docs/api-documentation/how-to/orders/

Thank you very much.

i have… what do you need

Yes, I need this as well. I would like a PHP page with the full code example to do a limit order. So I could hit that PHP page and it would place the limit order. I see the javacript code example, and that is great I can customize that, but I need a full code example. If anyone has this, please post it so I can get started!

maybe you should use my example server there’s a api plugin that i built that still works for v2

I would like to use your server but I want to code my own as well and need a full code example to create a limit order using PHP on a web server. Actually just need any working full code PHP example and I can customize it and get started… Please help.

I used this API to create a PHP application to interface with Alpaca and do some test trades:
https://github.com/JeffreyHyer/alpaca-trade-api-php

The API seems to work fairly well.

Below is a portion of code that I was playing with to test proof of concept to have PHP automate trades using the API above. I removed some of the formulas from it but you should get the basic idea…

<?php
    echo "\n";
    $symbol="aapl";
    $percent=1.50;

    $url = "https://elite.finviz.com/quote.ashx?t=".$symbol;

    require './vendor/autoload.php';

    use Alpaca\Alpaca;
    $alpaca = new Alpaca("Your Key from Alpaca", "Your Secret Key from Alpaca");

    //change for real trading
    $alpaca->setPaper(true);

    $space= str_repeat(' ', 3);

    $price = 0.00;
    $refPrice = 0.00;
    //read from positions

    $avgPriceAcc = 0;
    $avgPriceTick = 0;

    $tickCount=0;
    $isOpen=false;
    
    $symbol=strtoupper($symbol);
    
    
    echo "\nSymbol: ".$symbol."\n";

    while (true){
        //Read account cash and share balanaces
        $account = $alpaca->getAccount()->getResponse();
//print_r($account);
        $accountCash = $account->cash;
        $accountEquity = $account->equity;

        $positions = $alpaca->getPositions()->getResponse();
//print_r($positions);
        if (!empty($positions)){
            $positionSymbol = $positions[0]->symbol;
            $positionShares = $positions[0]->qty;
            $positionCostBasis = $positions[0]->cost_basis / $positionShares;
        }
        else {
            $positionShares=0;
            $positionCostBasis=0;
        }

        $orders = $alpaca->getOrders()->getResponse();
//print_r($orders);
        $activeOrder=false;
        if (!empty($orders)){
//Put code here to determine order status
            $activeOrder=true;
        }

        //$isOpen=false;
        $clock = $alpaca->getClock()->getResponse();
//print_r($clock);
        
        if (!empty($clock)){
        //    if (!empty($clock->is_open)){

            
            
        //  Not reliable for detecting open or closed market            
        //        $isOpen = $clock->is_open;
        //    }else{
        //        $isOpen = false;
        //    }
            
            
 
            if (!empty($clock->next_open)){
                $nextOpenDT=new DateTime($clock -> next_open);                
                $nextCloseDT=new DateTime($clock -> next_close);
                }
            $nowDT = new DateTime();
               
            $isOpen = false;
            if ($nextOpenDT>$nextCloseDT) $isOpen = true;            
            
            $timeToOpen = $nowDT -> diff($nextOpenDT) -> format("%H:%I:%S");
        }


        if ($isOpen){            


            /*
             *

            if ($price <= $lowRange && $accountCash>$price && !$activeOrder){
                $shares = floor($accountCash / $price);

                $alpaca->createOrder($symbol, $shares, "buy", "limit", "day", $price, null, null);

                echo $space."\nBuy ".$shares." shares". $space;
    
                $avgPriceAcc = 0;
                $avgPriceTick = 0;
                
                $refPrice = $price;
                $activeOrder=true;
            }
  
 

            if ($price >= $highRange && $positionShares>0 && !$activeOrder){
                
                $test=$alpaca->createOrder($symbol, $positionShares, "sell", "limit", "day", $price, null, null);
//              print_r($test);
                echo $space."\nSell " . $positionShares. " shares". $space;

                $avgPriceAcc = 0;
                $avgPriceTick = 0;                
                
                $refPrice = $price;
                $activeOrder=true;
            }
        
        } 
    }
