UPDATE 2018-01-26 20:58:26 My internet is shit trading will be delayed by 15 min

[NikhilPeri]

WE ARE LIVE! any issues now should be real

[arilotter]

buying stocks still throws a 500 for me

[dfsisinni]

[NikhilPeri]

^ looking into this, my internet is spotty so I will see if I can recreate it

[NikhilPeri]

Not a CORS problem, it was server side...fix just went out and 🎩 'd it we should be rolling

[arilotter]

@NikhilPeri Unrelated to selling, I'd like if you added CORS headers so I can call the API from the browser.

[arilotter]

The API is bugged: it does not show the actual value of remaining cash when you call /api/account, instead it always shows 10000000.

[arilotter]

Our account was reset, and all our holdings deleted. ????

[zako160]

^ same

[CSchank]

Can we get an api for only current amount and historical as a separate thing?

[dfsisinni]

our holdings keep disappearing

[NikhilPeri]

THERE WAS A MAJOR BUG IN STORING TRANSACTIONS...mostly cause by me not storing them, lol I have reset all account holdings and cash. and fixed the bug

[ColinNowers]

@NikhilPeri are you ranking the performance on cash value right now?

[NikhilPeri]

No it is ranked by total_value = holding + cash value

[z3t0]

There is a non conformance to the docs for one of the API call results. 'historical_prices' is actually returned as 'historical_price'.

[kimwoo11]

whats going on with the standings lol

[z3t0]

is the historical price at index 0 the most recent or oldest

[AcharyaS97]

Im getting a 404 error trying to buy

[NikhilPeri]

deploying the following fixes:

• working on a fix for the standings page i think my x and y axis are swapped 🤷‍♂️
• and a doc fix for @z3t0 ❤️

The historical price is index 0 is oldest

[SamTheOnionMan]

It's down right now too, can't access the main page to see the graph or anything.

[NikhilPeri]

can everyone add time outs between price calls...I have 2 webservers and I dont want to add a third

[Mogball]

90 stocks * 14 teams, checking prices every minute. Please Add a third webserver

edit: hotel wifi is making this hard enough already -- just bought another 1gb of data ecksdee

[NikhilPeri]

you cost me so much money... added a 3rd the down time was because of this

also to be fair i am currently using the shittiest servers heroku offers

[SamTheOnionMan]

What were the deleted comments about 🤔

[Mogball]

Get uOttawa to reimburse ;^)

[DanielCefaratti]

Do historical prices always include the current tick?

[NikhilPeri]

unless there is a weird race condition it should

[NikhilPeri]

the home view was kinda fucked...I think i fixed it 🤷‍♂️

[SamTheOnionMan]

not investing everything I had into JOE - worst mistake of my life

[CSchank]

It would be nice if this hotel had good internet....

[zako160]

is it me or is the market not updating

[arilotter]

it just updated, but it's definitely slow

[NikhilPeri]

Sorry I had to pause the simulation to scale up the sidekiq workers....but my wifi craped out so i couldnt restart it

done now! and added some more stocks TOTAL COUNT IS 160

[DanielCefaratti]

Do all stocks always fluctuate every tick? Or can they remain static?

[SamTheOnionMan]

they haven't changed in like 10 minutes

[SamTheOnionMan]

at least my portfolio hasnt

[SamTheOnionMan]

I need to talk to my accountant about that

[Mogball]

It takes me 5 minutes to query the price of all stocks, can you add an endpoint that allows us to simultaneously retrieve all stock prices? This reduces the load on both our ends

[DanielCefaratti]

Well I don’t know if that’s on purpose or because of the internet problems, I’d like confirmation

[Mogball]

I'm ticking on multiple threads and every 5-6 seconds it'll hang for 15 seconds then go back at it again

[NikhilPeri]

Maybe you should not query the whole dataset every-time and make some smart decisions

[Mogball]

This is "big data" problem, more data = more money

[SamTheOnionMan]

it takes like 10 seconds to query with this internet and we cant just watch like 3 stocks

[NikhilPeri]

right now I am runnning 28 requests per second and response time is about 2 sec per request I AM WORKING ON A PR TO THROTTLE PEOPLE MAKING LOTS OF REQUESTS this falls under the ddos rule so I suggest you re-think what data you "need" or prepare to see a slow down

[arilotter]

Stocks have different lengths of historical price arrays - for example, YIR has 135 elements and WHT has 142.

[NikhilPeri]

also no one said yo have to run this on you laptop....there were points for designing a system which can actually be deployed

☁️

[Mogball]

I brought an 8-core (x2 for hyperthreading) desktop

[NikhilPeri]

@arilotter stocks can be added an removed from the exchange depending on price, you code should be reseliant to this
