Let's talk about the ETH grid. The last small grid for going long on ETH just ended, running for a full 40 days. The range was very narrow, from 4200 to 4600, with 10 grids and 10 times leverage, resulting in a return of 70%.

Next, I plan to open a wide position in September, as a precaution against a significant downward reversal in the market. The risk for September and October has not actually arrived yet.

The lower boundary will be roughly set around 3400, and the upper boundary will be roughly 5200, around 30 grids. No need to be strict.
