Cant seem to trade clay or WTA

I cant make a green trade on clay matches or the WTA.I cant remember the last time I've seen a green screen since the clay swing started.

Im trying to mold my way of trading to always find value.To always trade with expected value as my basis to enter or exit a trade.But I cant seem to find any good strategies to apply in ATP clay matches or WTA.It all seems so random...
Everytime I pop up a live stream and watch a game,everyone seems to have a 50/50 chance of winning the game.Or a 50/50 chance of breaking the opponent/get broken.I know I can fare well in ATP matches in faster surfaces,but I cant for the life of me find a good strategy to apply in clay or WTA...


Little help anyone?
