Nope - the chart shows you exactly what I said - the result of trading activity.
MM's marking prices up and down is not trading. Same way walmart reduces cola by 50% is not trading. Therefore the chart does not show result of trading. It show the result of marking up/down.
If you insist on the price mark up/down is real trading, then you can't be trading yourself because you don't mark prices up and down at will like that. If you are not trading then you must be gambling.
