If your market data provider doesn't support historical Bid-Ask data you will see all historical trades on the Bid side.
E.g. Forex market doesn't provide historical bid-ask data.
These indicators can be adjusted for historical non-BidAsk data: mzFootprint, mzVolumeProfile, mzBigTrade, mzVolumeDelta. Choose 'Orderflow – Calculation mode' = UpDownTick.
UpDownTick calculation method is not very accurate. So, for some charts better to choose BidAsk mode to see exact live orderflow.
