What is the dark pool index (DIX)?

The dark pool index, or DIX, is a market wide percent of dark pool volume labeled as buy-side. On EZPZ it is one line titled DIX % Dark Pool Buyer Intent Over Time, plus Latest DIX, 7-Day Avg, 30-Day Avg, and Trend (7d). It is not a ticker tape and not a buy list.

Dark pool fills still hit the public tape after they execute. This page does not list those prints and does not rank names. It rolls the market into one DIX % series by Date. Latest DIX is the most recent percent. 7-Day Avg and 30-Day Avg sit next to it. Trend (7d) is a percent with an up or down arrow. The chart card is labeled DIX % Dark Pool Buyer Intent Over Time. The legend is DIX. Hover a Date for DIX. A dashed gold line is labeled 45% NEUTRAL. Historical Data lists DATE, Buy Volume, Total Volume, and DIX %. Info opens Dark Pool Index DIX, Reference Guide and Signal Interpretation, including a DIX plus DPI matrix. The 45% NEUTRAL line on the chart and the 50% notes in Info are two labels on the same page. Neither is a trade.

On EZPZ, the live chrome titles the page Dark Pool Index DIX. The subtitle is Institutional dark pool buyer intent, off-exchange accumulation signal. The range starts on 90D. Dark Pool Indicator (DPI) is a market wide pressure ratio versus the 20-day average with a 1.0 neutral line, not this DIX % series. Daily Dark Pool Amount is one ticker's Amount (M) versus Price by Date. Dark Pool Movers and Shakers is SPY Price versus running Buy Amount and Sell Amount. Dark Pool Net Flow is one ticker's Buy Amount versus Sell Amount plus Volume bars. Dark Pool Sentiment is Cumulative Net Amount (M) bars by Date. Block Trades Sentiment is Buy Premium (M) versus Sell Premium (M) by Date, plus Volume Sentiment. Largest Dark Pool By Ticker is one row per symbol for the session. Largest Single Dark Pool Trades ranks one print at a time. Dark Pool Sectors rolls the session into industry-group bars. Dark Pool Top Levels groups one ticker's prints by price. Dark Pool Flow is the all-ticker off-exchange tape. SPY Flow locks that tape to SPY. $1M+ Premium Dark Pool Flow keeps only million-dollar prints. $1M+ DP Volume Flow is the high dark-volume tape. Bullish Dark Pool Net Premium ranks names by Net Premium. Bearish Dark Pool Net Premium ranks the same Net Premium figure from the most negative reading. DarkVol Leaders ranks names by DarkVol Ratio %. Live Flow is listed options prints.

How Dark Pool Index works on EZPZ

Read Latest DIX first, then the averages, then the line versus 45% NEUTRAL. It is not a score. Most people start with whether Latest DIX sits above or below the gold line, then check Trend (7d). Change the range if 90D is too short or too long. Open Info when you want the DIX plus DPI matrix. Then open a tape page if you want prints behind a Date.

How this differs from daily amount, ranks, and the tape

Dark Pool Indicator (DPI) is DPI versus the 20-day average with a 1.0 neutral line. DIX is labeled buy-side share. DPI is volume intensity versus recent average. Daily Dark Pool Amount stays on one ticker and plots Amount (M) against Price by Date. This page has no ticker search. It is one market wide DIX % line. Use Daily Dark Pool Amount when you already have a name. Use this page when you want the market percent, not a ticker chart. Dark Pool Movers and Shakers is today's SPY Price versus Buy Amount and Sell Amount on the session clock. DIX is a multi-day percent, not a running session split. Largest Dark Pool By Ticker is one row per symbol. There is no ticker table here. Largest Single Dark Pool Trades ranks one large order at a time. Dark Pool Sectors is Highest Premium Inflow and Highest Volume Inflow, then Premium vs Volume bars. Dark Pool Top Levels stacks one ticker by price. Dark Pool Flow is the live tape with TIME, PREMIUM, DARK RATIO, and DIRECTION. $1M+ Premium Dark Pool Flow and $1M+ DP Volume Flow still show tape rows with a size floor. SPY Flow is SPY prints, not this DIX line. Live Flow is options, not equity dark pool index.

How people actually use it

Read Latest DIX against 45% NEUTRAL

Look at Latest DIX, then the gold line. A reading near 49% is a different picture than a reading that just jumped from 10% to 50% on the chart.

Compare 7-Day Avg to 30-Day Avg

Then read Trend (7d). A down arrow next to a 7-Day Avg still near 50% is a small drift, not a regime change by itself.

Change the window

90D starts on. Use 30D when you only want the recent path. Use 1Y or All when a jump on the chart needs more context. Custom days plus Go sets a count the presets do not cover. Ask AiPe to show the last 60 days if you want the range changed for you.

Open the tape next

This page is a market percent, not a setup. Open Dark Pool Flow for prints, or Daily Dark Pool Amount when you already have a ticker.
