Crypto trading bot for DEXes

Hello,
We are looking for a developer to create a crypto trading bot working on the DEXes (decentralized exchanges like DYDX and Uniswap).
The bot should be able to perform the DCA (dollar cost averaging) trading algorithm, explained below in general words:

1) It has a basic coin on the wallet (e.g. USDT) and a target coin it wants to buy (e.g. ETH)
2) It puts a buy order and buys some ETH, then immediately puts some other buy orders (lower) and a sell order for the entire amount of ETH (in order to get some profit determined by settings, e.g. 0,7%)
3) Then, if the ETH price goes lower, a new buy order is executed, and a new sell order (for the entire amount of ETH currently purchased) is being set in order to get the profit)

So the bot can:
- Take a user's settings into account and calculate a grid
- Perform sell and buy orders on the exchanges
- Work with some advanced settings in order to make the grid more smart and secure in a falling market

Detailed technical assignment and all explanations are to be given once we have a deal and start working.
Please apply if you have a relevant experience only.

Thank you.
