Moving Averages: Difference between Crossing over and Greater than

[stormy77]

I may be missing something. can anyone explain why the condition "crossing over" is different than "is greater than" in ToS scan option?
For example, the scan for "when 50 sma crosses over 150 sma" produces different results than "when 50 sma is greater than 150 sma"
There is a big difference in scan results. Since Tos gives both options, I'm assuming there is a difference

A script where the candle is colored:

Blue = moving average 21 crosses above moving average 8​

Magenta = moving average 21 crosses below moving average 8​

AssignPriceColor(
if FastMA crosses above SlowMA  then color.blue else
if FastMA crosses below SlowMA then color.magenta else color.current) ;

The result is ONE candle is colored where the exact cross took place. The "cross" is the beginning and end of the trend.

A script where the candle is colored:

Blue = moving average 21 is greater than moving average 8​

Magenta = moving average 21 less than moving average 8​

AssignPriceColor(
if FastMa is greater than SlowMa then color.blue else color.magenta) ;

The result ALL candles are colored when greater than

If you scanned for greater than, you would get all results above, even if you were at the end of the trend.
