Hello, I am new here. I have just discovered BitShares a few hours ago, read a few of the wiki pages and BitShares seems to have some interesting ideas. Because I am soo new I may not be understanding the request completely, but have described what I could provide below.

What I could provide is a data visualization of the correlation and/or cointegration between two different time series over an n period moving window. The data visualization could be in either PNG, SVG or PDF format. Just the data could also be provided in JSON or CSV format to be used for constructing trade logic. This could be done using a simple HTTP/HTTPS RPC or API call. The caller would supply the trade pair, n period moving window and what time resolution to use (eg. 5 minute, 1 hour, etc). The service would respond with either an image format or data depending on the suffix of the requested file (eg. .png, .svg, .json, etc).

I would like to implement this service as a way to get involved in the BitShares platform.

I just need to know how we could get started with this?

that sounds great but a little overkill for what bytemaster is asking. Basically the market can be bootstrapped if delegates inform the market as to what a "fair" price is. One could go to different exchanges and type the command in themselves based on what they saw on the website, or someone can use a python script to scrape the web (like you're doing) and then the script can submit the following commands to the bitshares client:

wallet_publish_price_feed ${DELEGATE} ${PRICE} USD
wallet_publish_price_feed ${DELEGATE} ${PRICE} GLD
wallet_publish_price_feed ${DELEGATE} ${PRICE} BTC

It's pretty simple, just will take some time to get it working right. You can then set up a cron job to keep it up to date.

so, he's looking for a simple python script:
1) scrape websites/grab json feeds/do whatever you need to do to get an accurate price quote at this moment (no history required)
2) send an RPC command with that information to a running bitshares client
