Trading indicators are very helpful indeed, but if we use many indicators in one layer it may confuse us,
that is my experience, because I used Tradingview, and tried to use 6 indicators, but unfortunately it didn't help,
and now I only use RSI and only the Trend line, yes indeed a trader has his own way
It helps but not necessarily we have to use them all, yes, some didn't work effectively, we'd better check the chart instead and do TA. And I believe these are more useful than those indicators. In fact, I'd spend more time analyzing the market trend.
RSI and MCAD are usually I'd used and which I found working.
But, in trading, this really matters in our decision-making and strategies. Even though we all are using the same indicator but the results are quite different, of course, not.
