  • Legacy: Time only -> hh:mm:ss.000 (ex: "21:11:50.627") Records are are *not* in chronological order, but instead sorted by raw timestamp which spans 2 calendar days.

• Bid Qty: Units of the Base Currency the market will buy using the Counter Currency. Ex: Pair = USDJPY, Bid Qty = 1,000,000 -> Market will buy 1,000,000 USD using JPY at the Bid Price.
• Offer Price: Exchange rate expressed in units of Counter Currency. Ex: Pair = USDJPY, Bid = 143.25 -> Market will sell USD for JPY at a rate of 143.25 JPY per 1 USD.
• Offer Qty: Units of the Base Currency the market will sell for the Counter Currency. Ex: Pair = USDJPY, Bid Qty = 1,000,000 -> Market will sell 1,000,000 USD for JPY at the Offer Price
