Free sources:

• WSJ market breadth pages
• Barchart
• TradingView
• MarketInOut
• Nasdaq official stats

Simpler alternative:

Use NYSE New Highs/New Lows.
It works similarly.

Many professional systems use:

$NYHL or $HILO
CountOfHighs and CountOfLows (as simple counts of “new high today” / “new low today”)

The backtester counts stocks making 52-wk highs/lows. If you have the market breadth series directly (New Highs, New Lows), you can use them without per-stock counting.

To mimic your weighted 9-day ratio with Excel:

K = Weighted highs (9-day weights 9..1)
L = Weighted lows (9-day weights 9..1)

In K10:

=9*C10+8*C9+7*C8+6*C7+5*C6+4*C5+3*C4+2*C3+1*C2

In L10:

=9*D10+8*D9+7*D8+6*D7+5*D6+4*D5+3*D4+2*D3+1*D2

NHNLRatio M10:

=IF(L10=0,9999,K10/L10)

NHNL signal N10 (1 if ratio > 1 else 0):

=IF(M10>1,1,0)
