Yes dear I am agree with you trading in D1 is very good, and this trading is for long term traders, and as we know in forex business there are many kind of traders and everyone has its own preferences, someone's are long term traders but sometimes they want instantaneous profit so they choose short time frame,
In this business everyone try to make his own time frame for his trading, but I think H1 and H4 these are very good for all of us, because we have not such a good capital in our account as well as it is depend on knowledge and experience and your trading strategies.
But according to my side I not recommend 1 minute 5 minute and 15 minutes time frame, because in this time frames we cannot judge the movement of market.
