In price action:

Support and resistance play a major role.
I need to teach you this, so you know when to take profit and when to buy, so you don't blindly follow my entry, stoploss and take profit.
Support and resistance hugely determines when to buy and when to sell.
Let me use $SOLV chart as an example.
The red line is the support while the green line is the resistance.
I called $SOLV for you to buy because it was seating on a support, you bought and made profit. But some of you who bought only sold because I gave you a starting profit target. But you don't know what happened behind the scenes.
Before that red dump, you can see that $SOLV tested the resistance three times and couldn't break it. Leading to the dump.
In other words, buy at support and sell at resistance.
NOTE: There are times trade doesn't obey support and resistance either because whales are pumping it or selling it helplessly, or because of other fundamentals.
I shouldn't be teaching you this because I do the math and analysis for you before I drop the signal but it's important you know so sometimes you can take initiative yourself.
