How to know BULLISH or BEARISH next day to CALL or not?

I tried trading on some tickers with my logic to determine the Stock Direction BULLISH or BEAR.
I looked at timeframe 2H and 4H (mainly 4H), logic:

1. Determine 4H Price > SMA20 then next day is BULLISH, should be CALL (conjunction EMA20 cross up EMA50 then strong market to CALL)
2. Determine 4H Price < SMA20 then BEARISH, don't CALL, should follow before PUT


I have been monitoring for 2 weeks and this logic satisfies about 80%.
