Market Maker Trading Bot

Project description: In the end, the bot should be able to send buy and sell orders. In order to do this, the bot must do the following: 1. The bot needs to be able to apply market making principles and hedging in a very fast manner within the APIs limit constraints. 2. Load a user-defined list of cryptocurrencies. Such list must contain the token symbol, and the amount to trade in Ether (ETH). 3. Retrieve market prices and order books for the tokens from step 2. 4. Retrieve ETH and token balances of the user's wallet. 5. If no buy order exists, post a buy order that is equal to the current price, so that the new order gets positioned as the best price for a determined cryptocurrency. However, the buy order will not be posted if the spread is lower than X% (defined in settings). If an existing buy order exists, check whether it is the best buy order. If it is not, cancel the order. This step should be repeated for all tokens of step 2. 6. Do a similar thing for sell orders except that the price has to be the lowest 7. The bot should be programmed in such a way that it continues to receive price updates for all tokens from step 2. 8. If a better, newer price is found, repeat steps 5 and 6. 9. Language: Python, Ruby, Golang 10. I want to be able to set limit orders/parameters. 11. Able to interact with exchanges APIs (for HGT) - Coss, HitBTC, KKCoin, GateCoin, Radar Relay, Lykke, Funcoin, EtherDelta, Shangya Exchange. 12. Needs to have a simple UI/Interface. 13. Able to interact with blockchain.
