I’m a new trader and does this set-up work long term?

Firstly on the 15m mark out Asian high and low, if London breaks the low I will head to 1m tf,look for a ifvg and place a long trade and vice versa.

Sl:- ATR value×2

TP:-ATR value ×4

So basically 1:2tp

Out of 100 trades 52 are wins. Should I also add HTF bias like 4H, if a 4H candle closes below the previous 4H candle then the bias is bearish and vice versa.

I have been trading since 6 months, no revenge trading, trade only if it follows all my rules etc. Currently I'm on demo and I will get a funded next year until then I'm gonna practice on demo and I make monthly around 2-5%.

I spend around 1 hr on charts, after waking up analyse and set an alert where I can enter a trade and same before going to bed. If the price enters into the zone then I will get an notification and I'll place a trade.
