    I have a Nodejs bot that is buying newly launched Tokens on Eth and BSC blockchains based on some set criteria. I need to add the following updates or features: 1) The bot MUST do all SELLS using the gas multiplier 2) Bot should restart if "sellThresholdFall" or "balanceCheckMultiplier" becomes true, or if the Bot Fails to Sell. 3) In Automagic, if useAuthorisedList = True, check "NoRug Endpoint" - a global Variable of Contracts, to see if the contract is on the list, only then buy it. 4) FIX needed = the % tracking is slow to update. Make it faster to track percentage gain. 5) If deadblock is true AND our Buy fails, the bot will listen for the first successful buy trade (from other traders), and sends a buy transaction. 6) If no activity (no buys or se...
