The BCC signal [SMADiff] is a momentum metric. SPY is higher than a year ago, and so [SMADiff] is Bullish. The math is based on simple moving averages, but reduces to the slope of the price curve (with the endpoints smoothed over 10 days).
https://gtr1.net/2013/?~altSMADiff26:h1::SMADiff:g...The RRS slope could be used. [SMADiff] was last Bearish between 20250410 and 20250508. The RRS slope was last negative between 20220503 and 20230308. Since 19251231, the signals [SMADiff] and [SlopeRRS] agreed 93% of the time. Both were Bearish about 30% of the time. Count of days:

is > 0 1 965 16607 17572
total 7736 17430 25166
A possible alternative to RRS is based on dividing the time period into thirds, and calculating the slope based on the first and last third. For example, with 210 days:
AltSlopeRRS210 = (sma(0,70) - sma(140,70)) / sma(140,70)
=== math ===
SMA0 = sum(P0 to P199) / 200
SMA10 = sum(P10 to P209) / 200
SMADiff = SMA0 - SMA10
200*SMADiff = sum(P0 to P199) - sum(P10 to P209)
200*SMADiff = sum(P0 to P9) - sum(P200 to P209)
This is equivalent to:
AltSMAD = (sma(0,10) - sma(200,10)) / 20
=== SMADiff definition ===
Create [SMADiff]: [Simple Moving Avg of closing g-prices over 200 days; lag=0 days] - [Simple Moving Avg of closing g-prices over 200 days; lag=10 days]
step0: [SMADiff] > 0
"The Simple Moving Average (SMA) Slope identifies whether the intermediate trend of the market is up or down.
1) Take the 40 week moving average (200 day) of the S&P 500
A.) later optimized by Zeelotes to 180 days
2) If this week's figure is better than that of 2 weeks ago, then buy (or hold, if in already).
A.) later optimized by Zeelotes to 7 market days
3) If less, sell or wait it out."
