Studying Breadth of the Market

Market Breadth - ADS (Advance, Decline, Same) feature in TrueData Cheetah is similar to breadth indicator. Breadth indicator measures the number of advancing and declining stocks using a mathematical formula. It reflects the market sentiments. Looking at  ADS,  a trader would get an idea about how a market is performing. It also has a third line 'Same line' which shows the percentage of stocks which are neither advancing nor declining, it shows stock with no % change in their close price.

Advance-Decline line can be better understood by studying convergence and divergence:-

Convergence

Bullish- when advance line converge towards decline line from bottom to above, then it's a bullish convergence. It generally shows signs of trend reversal in the market from bearish to bullish.

Bearish - when advance line crosses the decline line by moving down, it leads to bearish convergence.  This typically indicates a bearish reversal in the market.

Divergence

After convergence, ADS forming new highs or new lows. This can be used to identify a trend where fewer stocks are declining and the decline in the index may be nearing an end. Thus a trader can identify a stock in a group by using '% chg'  for trading.

Similar trading pattern could be followed in Bearish divergence.

Ratio

A/D ratio if above 1.25 shows a bullish trend in the market whereas if below indicates a bearish trend, if A/D ratio is between 0 and 1, this indicates bearish to choppy market. Using  A/A+D formula shows a strong bullish trend if above 0.60 or bearish trend if below 0.50.
