Project Overview

COINGUIDE : a webapp that aims to guide crypto traders on the most popular Cryptocurrencies. It achieves this by fetching records from poloniex using their api, rating these records according to their buy orders.

Coinguide aims to keep traders informed about the popular coins (coins which the highest number of buy orders within a specific time range). A future goal of the project is to become a reliable platform that accurately ranks coins/tokens based on how much traders and buying a selling using a mathematical algorithms. Coinguide isn't a website that gives investors financial advise on which coin to buy or not, it simply gets the required data from crypto exchanges's api processes the data using an algorithm and tells users the coins gaining popularity and those loosing popularity.

How I implemented this.

Making use of PHP Laravel framework gives me the flexibility and also utilizing the MVC architecture.

Model file

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Tradesatoshi extends Model
{
    //

    protected $fillable = [
      'id', 'coin', 'currencypair', 'buy', 'total_buy_trade', 'current_buy', 'last_total_buy_trade' , 'change'
    ];
}

Repository file handling the data and logic

<?php

namespace App\Http\Repositories;

use App\Tradesatoshi;

class TradesatoshiRepository
{

  protected $tradesatoshi;

  public function __construct(Tradesatoshi $tradesatoshi)
  {
      $this->tradesatoshi = $tradesatoshi;
  }


  public function saveData ($coin, $currencypair) {

      $save = Tradesatoshi::create([

            'coin' => $coin,
            'currencypair' => $currencypair

        ]);

        return $save ? true : false;

  }


  public function updateBuy ($currencypair, $buy)
  {

    $update = Tradesatoshi::where('currencypair', $currencypair)->update(['buy' => $buy]);
    return $update ? true : false;

  }


  public function updateTotalBuy ($total_buy_trade)
  {

    $update = Tradesatoshi::update(['total_buy_trade' => $total_buy_trade]);
    return $update ? true : false;

  }


  public function getAllCurrencyPair ()
  {

       $all = Tradesatoshi::select('currencypair')->get();
       return json_decode(json_encode($all) , TRUE);

  }


  public function getAllByLimit ()
  {

      $all = Tradesatoshi::get();
      return json_decode(json_encode($all) , TRUE);

  }

}

Controller file to handle request and renders the appropriate view with the model data as a response.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Repositories\TradesatoshiRepository;

class TradesatoshiController extends Controller
{

  protected $tradesatoshi;

  public function __construct(TradesatoshiRepository $tradesatoshi)
  {
      $this->tradesatoshi = $tradesatoshi;

  }

  public function getCoins ()
  {

      $coins = $this->tradesatoshi->getCoins();

      return $coins;

  }

  public function saveCoins ()
  {

      $coins = $this->getCoins();

      foreach ($coins as $key => $coin) {

          if ($coin['status'] == "OK") {

              $coin_name = $coin['currencyLong'];
              $currencypair = $coin['currency']."_BTC";

              $this->tradesatoshi->saveData ($coin_name, $currencypair);

          }

      }

  }

  public function getcurrencyPair ()
  {
      return $this->tradesatoshi->getAllCurrencyPair();
  }


  public function getMarketHistory ()
  {

      $currencypair = $this->getcurrencyPair();

      $total_buy_trade = 0;

      foreach ($currencypair as $key => $currencypair) {

          $currencypair = $currencypair['currencypair'];
          $market_history = $this->tradesatoshi->getSummary($currencypair);
          $result = $market_history['result'];

          $buy = 0;

          foreach ($result as $key => $summary) {

            if ($summary['orderType'] == "Buy") {

                $buy = $buy + 1;

            }

          }

          $update = $this->tradesatoshi->updateBuy ($currencypair , $buy);
          $total_buy_trade = $total_buy_trade + $buy;

      }

      $update_total_buy = $this->tradesatoshi->updateTotalBuy ($total_buy_trade);

  }

  public function viewMarket ()
  {

      $data['tradesatoshi'] = $this->tradesatoshi->getAllByLimit();
      return view ('markets.tradesatoshi', $data);

  }
