[Question] Is this the right place to start building a tool that can work with market data?

[cryptoeraser]

Hi,

I am a Coingy customer and was curios to know if I am at the right place. I would like to get familiar with building some simple web-app based tools. Those might involve displaying open orders, visualising open orders on a chart etc. Is this the correct place to start? The plan is to keep all of this JavaScript based (node.js etc.). The aim is to automate some of my trading activities.

Are there any limitations in terms of pulling all tickers, realt-time data to draw my own charts and plot custom indicators etc?

Thanks.
