OANDA Chart Viewer

How to Install

$ git clone git@github.com:hassiweb/OANDA-Chart-Viewer.git

How to Run

1. Configure your OANDA account information

You need to modify your OANDA account information and related information in ./scripts/oanda.conf. There is a sample file at ./airflow/app/oanda.conf.sample.

Parameters are as follows:

account_id: OANDA account ID
access_token: Personal access token which is issued by OANDA to use their APIs
environment: "practice" or "live" (see Interface OANDA’s REST-V20 in detail)
from_date: Initializing the database from this date (in RFC3339 format).
timezone: TZ database name (see List of tz database time zones in detail)
granularity: OANDA defined time granularity. (see CandlestickGranularity in detail)
instruments: A string containing the base currency and quote currency delimited by a "_". If you want several pairs, you can write multiple pairs delimited by a ",".

2. Configure your InfluxDB information (optional)

If you want to use a specific InfluxDB server, you can change the configuration for InfluxDB server in ./airflow/app/influxdb.conf.

3. Run docker-compose.yml

Let's start the services by the following command.

$ docker-compose up -d

4. Initialize and update the database

This application uses Apache Airflow to manage scripts to initialize and update charts. Web UI is provided via "localhost:18080" as follow.

Once turning the switch of the "initialization" tasks on, this task is going to retrieve chart data from from_data which is specified in oanda.conf. After that, please turn the switch off because this is not needed to run repeatedly.

By switching the "update" task on, this task is going to retrieve the latest chart data repeatedly.

5. Show candlestick charts

Let's open a browser and type "localhost:13000".

You can see four pre-configured panels for "EUR_USD", "USD_JPY" and "EUR_JPY" pairs. If you selected a different pair, you need to change settings.

However, it is impossible to override the provisioned panels by an InfluxDB restriction. Here available options will let you Copy JSON to Clipboard and/or Save JSON to file which can help you synchronize your dashboard changes back to the provisioning source (see here in detail).

6. Update charts (optional)

This application manages scripts to update the chart by Apache Airflow.

When opening the Web UI of "localhost:18080,"

Components
