Moreover, i also discovered that almost all the indicators work best on the long timeframe like weekly or monthly timeframes. If you want making trading decisions with peace of mind? trade only on those timeframes with any indicator and you will make money.
What that matters is what trader are you.
Scalpers will prefer to use the 15 minutes candles instead. But day traders will prefer the 4 hours candles. Swing traders will prefer the 4 hours to a day or 1 week candles. Holders will prefer the monthly candles also.
Were the different categories of traders with different names? I didn't know that, thank you for enlightening me tonight.
I find it extremely risky to use 15 minutes, 1 hour, 2 hours or 4 hours candles, these time frames aren't a good indicator of what's coming up but from my experience, weekly and monthly charts are better indicators. You can see that during a year or years, price goes up and down and if you are a long-term trader, it can usually ease your mind.
Maybe for OP it works always on long term but in short term fundamental analysis is not always work.
I think that strategies don't work short-term. They might work for a limited time and in certain timeframes but your strategy can be ruined anytime because any news can significantly pump or dump the price. This can ruin the calculation that you made with short candles.
