Crypto trading bot

I need a trading bot, it should buy and sell crypto based on the pricing set by me. Also should signify different crypto. So it needs to search what Crypto the platform it uses and can set the buy and sell price. There are many platforms so I’ll be letting you know once bid and I will message you.
Need a trustworthy person to bid on this project and also need to sign NDA. Developers should create their own trading accounts so they can test it.
