I can develop Cryptocurrency Trading Exchange platform where customers can trade cryptocurrencies or digital currencies for other assets, such as conventional fiat money, or different digital currencies. This Exchange platforms match buyers with sellers. When a market order is selected, the trader is authorizing the exchange to trade his coins for the best available price in the online marketplace. With a limit order set, the trader directs the exchange to trade coins for a price below the current ask or above the current bid, depending on whether s/he is buying or selling. Also I will make trading robot, which will do all work for you. You just need to click start trading button and everything will happen automatically, trading bot will automatic generate BUY and SELL signal from technical indicators you will choose.
