Development of bitcoin FX trading tool

Thank you for your proposals. It is a function I want for trading tool, 1. Make the order same as the order in Account A of BitMEX also order in Account B of BitMEX 2. Reverse the purchase / sale position of the order in Account A of BitMEX and have it order in BitMEX's Account B Make the order by changing the quantity, such as ordering in Account B by 5 times the quantity of the order in Account A of 1 and 2 Functions 1 to 3 can be Web application or Windows application. I would like to realize it with a configuration that minimizes time lag as much as possible. In addition, because we use it for multiple users, multiple accounts, we would like to prepare tools or sites for centralized management of them. I would like to realize the trading tools and management tools and sites in such a way that administrative cost costs are as small as possible. Could you estimate expenses and periods, including proposals for the overall system configuration? In addition, please estimate also when you correspond to both BitMEX and bitFlyrer when you set the exchange as bitFlyer. If you have any questions, please do not hesitate to contact us. Thank you very much.
