There has never been just one way to get on board; the key lies in which path you choose that matches your style.

Some people like to follow the trend lines drawn subjectively to catch the pullbacks and get on board earlier, but there are also many false signals, and it's hard to find a good stop loss.

Some prefer to wait for the price to reach the support zone before confirming their purchase, which is stable and reliable, making it easy to set stop-loss orders.

Some people only focus on trend breakthroughs, placing more importance on confirmation than anything else, which is the safest approach, but the profit margin is often partially eaten away.

There is no absolute superiority among these three methods; the key lies in how you balance "sense of security" and "getting on board efficiency," or weigh "profit-loss ratio" and "certainty."

The truly mature approach is not to get caught up in which one is the best, but to be clear about which one to use in different market conditions.
