Dynamic Currency Pricing API

This project contains the following functionality:

1. Transaction Matching Algorithm
2. Coin Pricing Algorithm
3. Verification Backend

Transaction Matching Algorithm:

Created a thread that ran the Transacton Mathing every minute. Used SQLITE3 to store all the transactions.
Following Tables were created.

1. Buy_coins
2. Sell_couns
3. matched_txn + sell_txn + buy_txn
   Transacton matched and stored for users to query and retreive

Used Python-Flask and deployed on heroku/AWS-EBS

Coin Pricing Algorithm:

Dynamically price the coin according to to the current market sentiment(Twitter) and demand and supply gap.

Market Sentiment:

• Positive news increased the price, negative decrease it.
• Weights are given to user
  - If verified account/celebrities -> More Impact
  - If Followers>Following -> Impact according to ratio
  - If Following>Followers -> Less or negligible impact because can be spam accounts
• Created custom formula so that prices are stable and not fluctuating randomly or frequently in minutes.

Verification Backend:

Used a combination of python-flask and AWS S3

• Documents of users uploaded to AWS S3 and verification set through python flask on heroku/AWS-EBS
• Verification admin manually verified users and sent verification confirmation

Pricing Algorithm and Matching algorithm are running as daemon threads
