Yes, this is nothing but trading bots. There are many of them are available in the market but I'm not recommending them to use. Bots usually do analyze previous day high, low and close to give predictions but I am not sure they will recognize pattern formations.

Line charts are good tools to make predictions by analyzing pattern formation whereas candle stick charts are giving some signals for every time period. But I am not sure a bot will come versatile to do these all automatically and I believe relying them for making decisions for our trading will be giving no different results what we are getting the trading bots.
