I agree with you but there is nothing to do when the market suddenly crashes after you invest. Today suddenly the market has crashed so much that after investing I suddenly entered the market and saw a big fall in this case I did not get enough opportunity to do market analysis. Those who want to invest right now can definitely invest in this DIP market and wait for the next Bullrun.
Market now temporarily Crashed, Do Your Own Research (DYOR)
What you see on the chart is not the real definition of a dip...maybe I have to ask you how you were able to know that's a real dip.
I think there are some questions you need to ask yourself before concluding that you have seen a dip and you needed to buy. Take a quick look here;
1) Does a sudden crash in price literally means a dip? Can one buy at that price?
2) What's the market structure of the current market?
3) Could the current price be a fake out or a real move?
4) What timeframe is to be used to know the real movement of trend? Most time using higher timeframe is better to avoid market wrong decision.
5) What kind of trader I am? Scalper, day trader, swing or position trader? The kind of trader that you are would determine the kind of time frame to be used in the market often.
The above question need to be answered so it would guide you not to take the wrong step in the market as a trader. We are in the market to learn and make profits. If we don't learn, we might keep getting the adverse side of the market, that is why it's good to keep learning as we are trading.
Learning and debugging our trades is very important!
