Bear, this change was implemented before you expended your money, as I checked all portfolios prior and they had reduced / small new investments overall.
Lets be honest here... you don't need a week to rework anything, because you're simply screening pre market shares, maybe assessing volume, and buying them at closing price before market opening, as pre-market prices aren't included. As I said, it was too easy to manipulate based on being around just for one market opening myself.
15 days holding onto shares changes nothing beyond immediate buy and sell strategy within the same day period, and not weekly strategies. A 15 day hold only increases the risk of what goes up for profiteering, usually also comes down again within a week after the fact, hence the introduction of the lockout period to stop such manipulation occurring.
You have been fully aware of it, as we have discussed the limits of the software for gaming purposes already.
After using it once upon opening myself, I would be negligent if I didn't make it more game oriented versus its current high state of manipulative means, just as I did for sportsbook on finding loopholes in that system for myself. That game has also now changed so that you can, and will, lose.
