DooPHP Forex backend for enyo-forex charting frontend

* Designed to be used with free forex data from http://truefx.com and highstock charts http://www.highcharts.com/products/highstock

##Objective:

Load raw tick/quote data [realtime & historical] into a MySQL Database. API outputs JSON aggregated candlestick data, including custom technical analysis indicators.
All candlestick time windows [s,m,h,d,w,M] are supported. Candlestick data is cached on demand in local Redis instance (in memory) except for weekly and monthly time windows.
* Custom Indicators can be built by adding a new class/file:

```
doo-forex/protected/class/Technical Indicators/
```

###Quick Start:

##Installation:

* Install dependancies:
  * MySQL Server 5.6+ [requires millisecond datetime]
  * Redis Server 2.4+ [used for in memory on demand cache]
  * screen [optional for running forex updater]
  * php-cli
  * php-pdo
  * php-mysql
  
* Install Doo PHP Framework http://doophp.com/
* Clone doo-forex and init submodules

```
git clone https://github.com/hurdad/doo-forex.git /usr/share/doo-forex
cd /usr/share/doo-forex/
git submodule update --init
```
* Configure Doo Framework path:

```
vi doo-forex/protected/config/common.conf.php
```

```
$config['BASE_PATH'] = realpath('..').'/dooframework/';
```
* Configure Apache alias:

```
vi /etc/httpd/conf.d/doo-forex.conf
```
Example configuration with install path : /usr/share/doo-forex and url : /doo-forex
```
Alias /doo-forex /usr/share/doo-forex
<Directory "/usr/share/doo-forex">
  AllowOverride All
</Directory>
````
Note: you will need to modify doo-forex/.htaccess 'RewriteBase' if you use another url

* Install Database Schema

```
cd /usr/share/doo-forex
php install_db.php
```

##Backfill Historical Data [Optional]
  *  Download free historical data from truefx : http://truefx.com/dev/data/
  *  Unzip to .csv
  *  Load into database

```
cd /usr/share/doo-forex
php cli.php forex_loader /path/to/EURUSD.csv
```
Note: you will need to manually run hour & day aggregations for any backfill'd data

```
php cli.php quote_aggregator day EUR/USD '2012-01-01'
```

##Start Forex Update with hour and daily pre-aggregations enabled

```
cd /usr/share/doo-forex
screen -A -m -d -S forex php cli.php forex_update 1
```
