What is better for this is to have a bot where you can automatically buy when certain conditions of your strategy have sufficed. Maybe with those three indicators that you have, RSI, MACD, and BB, you can all together just buy it and then wait for the percentage to sell.
I mean it is not a bad idea, but would you trust it? I would trust it to send me signals if that is what we are talking about and I have one, that's called tradingview and it doesn't really make any mistakes neither, sometimes it freezes and not work because of ddos issues but the reality is that it's mostly working. The only addition could ever be making it easier and simpler to use, and that would benefit people who are not like us, who studied the charts and indicators.
I would say it may work for the newbies and they could use it for signals and make it easier but that would still be for a smaller member group. If we are talking about making the trades for us that would be trading bots, they do that based on indicators as well so it already exists. Not really an idea that is brand new basically, sure it's going to exist but that doesn't mean that it's going to be a fresh idea, this already exists, you can make it better but not inventing new thing.
