Smartcontract script for buying and selling token in same block

Phase 1:

I am looking to make a script which allows me to buy and sell a particular token/coin from pancakswap (bsc) in the same block

Script must be embedded as smart contract and should not require the use of nodes

There should be a front end allowing user to input

Token contract address
Buy amount in wbnb
Wallet address
Private key for wallet
Slippage as default for token

Once phase 1 is completed and tested, phase 2 will begin which basically will be extension of phase 1:

Phase 2:
The script should only buy when certain conditions are met on technical analysis ie rsi, macd, ema etc. Setting will be entered by user in front end for example rsi is more than 0 etc, full details will be provided to coder

End software will run on vps/cloud server

This is an on going project and require support on monthly basis for tweaking and tuning. We will agree a monthly retainer later once work is done

Important information:

Only bid if you have technical knowledge of smart contract, pancakeswap etc

Do not ask me for upfront payment or money to test the system

Do not ask me to pay offline

Milestone will be created one at a time for each phase. Payment will be released as work is done
