Arbitrage bot in cryptocurrencies

Hello, I am looking for a developer with good knowledge in trading and especially in arbitrage to develop a bot that can search for different arbitrage opportunities in different cryptocurrency exchanges and can automatically do the corresponding trades transactions. I would like the bot to work on a Linux or Windows VPS. It will have an interface either web or software. There should be the possibility to let him automatically search or to indicate to him even the pairs on which to arbitrate. The bot must be able to take into account the trade fees when calculating profit. For exemple: [login to view URL] I would like to have already configured or less 5 exchanges and have the opportunity to add other exchanges in the code using a tutorial or from an interface. The arbitration method that must be followed corresponds to this: [login to view URL] Of course, there are already many arbitrage bots. I'm looking for the best speed of execution regardless of the programming language chosen. Finally I wish to own the right to the sources of the software and that this software is not resold to others. Feel free to add examples of work of the same type that you would have done.
