I need a solution for my own 'crypto trading+exchange platform

Starting from scratch, I need a solution to develop my own crypto trading and exchange platform. This platform should compare prices across various exchanges like Coinbase, Binance, KuCoin, and Unocoin, as well as different cryptocurrencies. The solution must identify opportunities to buy on one platform and sell on another for a profit, transferring funds to my personal wallet instantly for security. The bot should only execute transactions if a profit is guaranteed, factoring in all platform fees. The platform will be invite-only and not open to the public, but I plan to generate profit through referrals on my website.

Please advise on what I need and how to make this happen. Additionally, I am interested in understanding how you can ensure that this concept will be profitable for me.
