Yep. Generally I'm adding or trimming in about 10% increments to the position. Minus signs indicate selling while plus signs are buys. The "cash" is shown in green while equity position is in red. So, you can see the correlation between changes in the cash reserve each time there's a trade. The lower graph is "stacked bar" so shows the sum of the cash and the equity value so the top of each bar is the total value for that week including then current cash.
It makes stock ownership more like "inventory control" as I maintain a core position all the time and just trim and back-fill. Think of it as running an "Equity Warehouse."
