I'm working on a Python program that generates a price based on random movements, but I'm noticing that the price often ends up smaller than expected. In my code, I use a random factor to determine whether the price should go up or down, but it seems like it's stuck on decreasing. Can anyone help me understand why this happens and how to fix it? I'm particularly confused about how I'm manipulating the variable 'x' and how that affects the price calculation. Any tips would be appreciated!

I think the issue might be the section where you do `x *= -1`. When 'x' is negative and you multiply by -1, it becomes positive, but in some cases, it may lead to values greater than expected, leading to unexpected price changes. You might want to add a check to keep 'x' within a certain range.
If you're looking for more stable behavior, consider adjusting how much 'x' can influence the price change. Right now, that random factor can swing pretty wildly, leading to large decreases. Maybe limit it to a function that keeps changes more gradual.
It looks like the variable 'x' has some tricky calculations. When you have `x = -1 + (-math.log(1 - random.random())) * 0.1`, if 'x' falls below zero, you end up with negative values after multiplying with 'Price'. This could be why your new price is decreasing. Try ensuring 'x' is always positive before doing the price calculation.
