Hello pinabetal,
Good questions.
I was in a trading room with a technical analysis discretionary trader just learning and follow his trades.
After trying and watching most indicators (ema, rsi, macd, etc) and the candles (price action), I always noticed that the actual price on the chart would move in the direction before the emas would change.
It was like the indicators was always behind the actual price. The indicators was lagging the actually price I was seeing on the chart. It was like "why I am waiting for this indicator line on MACD to cross up when price is already move up, I am going to miss a good entry" Plus it was there numbers in the indicators that confuse me. Like which number to use and why. Do I use the 7 ema, 8 ema, 20 ema, 4 rsi, etc etc.
Indicators was just a bit confusing at first. Maybe I was still learning and in-patience.
My simple thought process was "why do i need indicators, if I see the price moving up or down, like its right there, price is moving and here are the indicators following price by x amount of seconds, these indicators are useless"
So I took them off of my chart, cause they lagging price, I don't need them to tell me which direction price is moving. I see the price moving up and down clear as day.
I notice price would stop at these support and resistance, and thought my self, if price is moving up and goes above this resistance I see price struggling with, why not just get on board when price get above this resistance at decent entry where I can put a stop loss.
And that's my rationale for only using candles in conjunction with support/resistance.
NOWWW, fast forward 3 years, after learning alot, I would like to move more into automated trading, proper back testing and data collection/analyzing and my manual way of trading I can not code "my eyes see price going up, so get long". Therefore an indicator(s) makes sense now.
Interesting, well I think some indicators do a lot better if you understand better how accumulation and distribution works, not every indicator is bests used by simply immediately entering a position just because it gave a buy or sell signal or had a cross.
Not only is it important where the signal took place, sometimes you have to be patient for an entry. This may seem obvious, but I haven't personally seen a lot of talk about this, most of the time when people here "buy or sell signal" in my experience they think to immediately take a position and expect green in there account balance.
