How entry, target & stop loss prices are calculated

I have always wondered what tools/techniques are used to determine a trade's entry, target & stop loss prices a day ahead? I have seen such trade tips/calls (never blindly follow them toughly) and few of them are almost accurate.
My question is - Which technical analysis tool/indicator is used to forecast tomorrow's price action? All indicators that I have come across works on a live trade (i.e., during actual trading time) but I am keen to know what is takes to make a list of stocks and decide on the entry/target prices a day ahead.

I mostly do intraday trades & would like to learn how to make a list of stocks that will move tomorrow & decide on the entry & target prices. Googled on this but mostly such projections positional. I would like to know what works for Intraday.

Need expert advice. Thanks.
