I took a similar approach to yours.
I am long on all my positions and use pies as a DCA strategy on the positions I consider that I don’t consider selling before 20y.
My ETF pie is mainly oriented on Growth (vs Value on my dividend growth pie), I prefer to use ETFs than to have a 50 high-growth companies pie as I used to have.
For shorter and mid-term movement, I prefer not to use pies and simply put a limit order (<5% of my total portfolio).
