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.

For Forex pairs use relevant futures to enable all features of MZpack in your analysis (including DOM analysis). E.g. for EURUSD use 6E futures.
