Do I read it right? They list 716 Nasdaq-100 strategies? 339 momentum strategies?
Wow.
Although I guess there is some overlap.

Can you decode some of the terminology for us?

For example, the highest of the Nasdaq ones, "Nasdaq-100 Eom Momentum No-Gate" algo-catalog.com - Ndx eom momentum nogate
Looks pretty easy to run if we know all the definitions.

Parameters:
TopN:	8
Win:	126

Data:
Rotate:	EndOfMonth
dret:	C / C[1] - 1
zmidr:	((H + L) / 2 - (H[1] + L[1]) / 2) / Max(C[1], 0.0001)
zvoln:	V / Max(Avg(V, Win), 1)
zeom:	zmidr / Max(zvoln, 0.1)
fscore:	Avg(zeom, Win)
trendUp:	C > Avg(C, 200)
rankS:	#Rank IF(InNDX and trendUp, fscore, NaN)

My guesses:
C is current price
C[1] is previous price 1 [day?] [month?] ago
H = hi
L = lo
H[1], L[1] is High & Low 1 unit ago. day? month?

Would that be month? Since this trades monthly.
So H is the high price of the just finished month and H[1] is the high of the month before that?

V = Volume [of this month?] [of the current day?]
Avg(V, Win) = Average volume of the last 126 days.
Avg(C, 200) = 200 day SMA
Avg(zeom, Win) = Average zeom of the last 126 days.

dret = Daily return. Today close vs. yesterday close. So "[n]" means "n days ago"?
zmidr = something something of the month? day?

It seems odd to trade monthly based on the prices & volume of just one day.
