Naughty F::Q ... don't be silly, the notion exists, it got used but not 
implemented.  I don't think we (gnc and other people that use F::Q) 
should presume they should protect us from being bad citizens.

And something else, the 6 seconds is growing, 16 seconds, maybe 61 
seconds soon, I don't know what the back off should be but I know for 
sure gnc is not suitable for trading (by that I mean prices within a day 
or maybe within a few days).

I certainly know about that one and expect most people experience it 
ordinarily in buying food, etc

I think an actual price overrides.

>Sources to the right can replace sources to their left 

my reading of what you are saying is that the price-editor should 
override the actual, but I'm not convinced that is really what you mean.

Hmmmn, I'm going to pause and think about that.

I think that is a wrong-thing: I think the actual human level price is 
the price for the day for a person or small or modest sized organisation 
rather than the price editor price, if you toss in the ordinary stuff 
like some people and organisations can't get prices at the moment, what 
do you think is the right price for the day?

Is it the market price (big wide world) or the price they could achieve 
at the time on the day they attempted to get a price?

I am genuinely unsure about this, JohnR [99] , I think the price I have 
for something must be the price for the day *because* the gnc model of 
last price falls apart if it is supplanted.

[99] and other sensible commentators, remote as they may be

I live in London, I don't vote for Trump, if it matters I think Brexit 
is dumb, I have access to market prices.

I'm generally ok with a price a person creates being prime (if I buy an 
option on DogFood and Wall at USD200 per kg of federal_employee that is 
my price for supporting Trump, right?) [1]

> I don’t want GnuCash to make assumptions about what F::Q does internally, 

My break: I agree

I also think it will be very expensive for gnc and similar applications 
that utilize F::Q to start from scratch.

doesn't gnc do that anyway? if that wasn't true we wouldn't be fucking 
about choosing which source we wanted a quote from, FFS

> 2 Check for prices for today, splitting the above list into have-price and don’t-have-price

I think this is a good approach but it breaks if many people ask the 
same question at or about the same time or repeatedly.

I don't know the answer to gnc and F::Q *not* being asked

alphabet share price

I don't use gnc or F::Q for that but I expect many people do.

Almost, I think the person should get a list, similar to the one 
presented at presented that says,
"we couldn't get the price for
FuckwitAndCompany
MayAndIdiots
CorbynAndWeird"

but instead of asking the dumb question about storing the prices it may 
have obtained

think about this

at the moment the gnc model gets good prices and throws them away!

How fucking idiotic and Trump like is that?

You have information?

What is the best thing to do?

I know!  Discard it!

Duh

Sensible people store information, prices, etc  why is gnc *discarding* 
what it does get?  I simply don't understand this.  Maybe someone else 
is whacking F::Q for a perfect complete set of all their data and 
someone else is just trying to work out if their small business is 
likely to get fucked by Brexit.

Why does gnc not store the prices it did get and then ask "do you want 
me to try again, the sources may be fucked, I may not be able to get a 
price again for a day or so because the fuckwit Trump is holding things 
up" or whatever excuse you have but here is the question

WHY IS GNC *NOT* STORING PRICES IT DOES GET?
WHY IS GNC *DISCARDING* PRICES WHEN WE KNOW THEY ARE BECOMING MORE 
EXPENSIVE?

> 4 Wait 60 seconds and request the have-price list.

if someone needs minute by minute prices I think they should pay for 
that,  I'm ok with once a day at best.

> The code would go into libgnucash/scm/price-quotes.scm.

at which point it would be obscure to me.  I'd know if it worked or not 
afterwards so who are you trying to impress?

[1] Trump has moved beyond stupid to plain funny, OK? [2]
[2] This is nothing to do with Rep or Dem any more, this is supporting 
the incompetent because you're a cheap white that never had anyone to 
vote for before, yay for you [3]
[3] I'm cheap white too, in case it matters [4]
[4] I'm also from africa, as in born their and tired of other whites and 
their rights.
