cryptocurrency autotrader

Hi, i'd like to have a BOT (interface not really important as long as it works) to place order on exchanges (yobit, coinexchange and cryptopia) i want to enter the information as how much of a coin to buy and the bot would execute the order immediately (buying the coin at whatever market price it is, SPEED IS IMPORTANT, it has to be able to execute the order fast) and automatically place a sell order at a specified % above the buy price For example: The first screen will ask me which exchange to use - I select yobit Second screen will ask me at what % i'd like to sell the coin - i set on 20% next screen.. how much BTC of my balance i'd like to use - I enter 1 Next.. coin name - LTC If the next sell order price is 0.2 the bot needs to buy 5 coins immediately and place a sell order for those 5 coins at 0.24 ---extra: I'd like to get a quote on another program (it can be the same just different option) The program would buy a coin at a specific price and market (probably gdax on this one) and would watch the price in real time and place sell order if a target is reached FOR EXAMPLE I want to buy LTC at $100 and automatically place a stop loss order at $75 IF the price goes up to $125 i'd like the bot to automatically change the stop loss order to $100 and so on I think i've entered all the details above the only thing i'd like to add is that i'd like to enter the API keys myself thanks
