Market Indicators for Outstanding Orders

Outstanding orders are the buy/sell orders that are currently placed into the book and not yet cancelled/executed. They constitute current liquidity for the buy and sell side, accordingly. The distribution of orders across different price tiers, as well as their longevity (age), can be helpful discovering a buy or sell interest in the stock.

Market depth

Indicator	Value	Description
VolumeA	Number of shares	Total volume of currently outstanding orders
VolumeE	Number of shares	Volume of orders at the best (edge) price
VolumeQ	Number of shares	Volume of orders within 0.25% price range from the edge price
VolumeT	Number of shares	Volume of orders within 0.33% price range from the edge price
VolumeH	Number of shares	Volume of orders within 0.50% price range from the edge price
Volume1	Number of shares	Volume of orders within 1.00% price range from the edge price
Volume3	Number of shares	Volume of orders within 3.00% price range from the edge price
Volume5	Number of shares	Volume of orders within 5.00% price range from the edge price

Weighted Market Depth Layers

Indicator	Value	Description
PVolumeE PVolumeQ PVolumeT PVolumeH PVolume1 PVolume3 PVolume5 PVolume10	Number of shares	These indicators are constructed for the 0.25%, 0.33%, 0.50%, 1.00%, 3.00%, 5.00%, 10.00% market depth layers accordingly by weighting the number of shares depending on the distance of the order to the edge of the book. The farther the order price from the best price, the lower the weight assigned to this order's share count. The best orders receive 100% weight, the worst orders receive 0% weight. This weighting mechanism allows to reduce volatility from less significant orders placed too far away from the bid/ask price to affect any short-term price movements, and results in smoother liquidity estimates.

Price

Indicator	Value	Description
PriceOpen	Dollar amount	Bid Price (for buy-side of the book) or Ask Price (for sell-side of the book) at the beginning of the tick period
PriceClose	Dollar amount	Bid Price (for buy-side of the book) or Ask Price (for sell-side of the book) at the end of the tick period
PriceLow	Dollar amount	The lowest Bid Price (for buy-side of the book) or Ask Price (for sell-side of the book) during the tick period
PriceHigh	Dollar amount	The highest Bid Price (for buy-side of the book) or Ask Price (for sell-side of the book) during the tick period
