Day trading: In a trend, the market determines the strength of every rise and fall. What we can do is, at relatively key positions, use stop-losses to probe and test an entry; if it goes right, take profit and exit, and if it goes wrong, trigger the stop-loss and leave the market—then find the next entry point. That’s all there is. No regrets about every move—only wanting to earn, not accepting losses—you’ll only lose even more.
