Q: When I compare your 620 chart to what I have on Stockcharts they are quite different and I don’t  know why. Stock charts lags and would not trigger the buy this morning until much later than what your chart shows. Just curious.

G: My charts include after-hours and pre-open trading, that’s probably why they’re different.
