Getting AgX scheduled jobs ready

On my previous posts about AgX, I have first extracte STEEM/SBD data to calculate their 200 days moving average (AgX factor), and then used this data to draw a chart of the evolution of the price ratio and of the AgX factor itself.

The task was then run manually with npm run start

New Features

• In order to automatize the whole thing I have integrated Express.js framework and set the main route to start fetching data and drawing the chart.
• The call to the the job is secured by a secret token
• If a chart has already been drawn that day, the process aborts
• If a chart has already been drawn that day but the admin wants to override, he can add the parameter force=true to the URL

The new flow is as follow:

• API is called
• Authentication is checked thanks to the token
• If Authentication succeeds, check if the chart has already been drawn
• If the chart has not been drawn yet or if the admin forced it, get data from Bittrex API
• Calculate 400 days STEEM/SBD ratio and 200 days AgX factor
• Draw chart
• Store it in public folder

The chart has been improved to follow @aggroed suggestions:

• Factor renamed to AgX
• Tooltip shows today values for AgX and Steem/SBD ratio

Next steps

Next step will probably be the final one and will integrate Steem.js to allow the backend to publish posts containing the AgX information.

Release coming soon!
