每日 23:00GMT 准时开放交易 (Open trade daily at exactly 23:00GMT)

Try this one out. Buy AUD/USD everyday at exactly 23:00GMT at open of candle but if you see trend is strong for sell, sell AUD/USD. Target 20 pips (less 3pip spread). S/L 20. There are always more buy opportunities during this time that are profitable than sell. But of course, this is not a guarantee that it will work indefinitely. Markets do change.

Note: When trading this way, my minimum profit was only $100 bec. of my broker's 6pip spread and $70 commission. So price has to move 23pips from my open position. That is why am looking for new broker with less spread and no commissions

I just use 5 EMA(close) to see trend.
