I am trying to count the number of days when BOTH the volume and close is above previous days', but the count multiply is erroneous.

Fetcher[ set{v, volume above volume 1 day ago}
set{p, close above close 1 day ago}
set{pv, p*v}

show stocks where ema(10) crossed above ema(50) within the past 30 days
and count(pv,10) is above 6
]

siliconhippy,

VERY CLOSE!

What you need is the count() function in the set commands:

Fetcher[ set{v, count(volume above volume 1 day ago,1)}
set{p, count(close above close 1 day ago,1)}
set{pv, p*v}

show stocks where ema(10) crossed above ema(50) within the past 30 days
and count(pv equals 1,10) is above 6
]



The count() makes the values of p and v zero (false) or one (true), so pv will now be zero (either/both false) or one (both true).

HTH,

C

thx again. Now this shows why we need good documentation, that not only states the commands, but TIPs the users too about pitfalls.
