02:20 <SnoopJeDi> UmbralRaptop, I was just googling 至上最強 because I was curious if it was an idiom, and I found this: https://www.youtube.com/watch?v=TvKhmXF9Qn0

02:20 <kmath> YouTube - 至上最強のゴールキーパーが現る！

02:21 <SnoopJeDi> idk why but ゴールキーパー is a funny gairaigo to me

02:43 <SilverFox> so my bot does stock stuff and Im looking at adding in the average effective price for a set stock figure, so if you buy 1 of a stock, its average is whatever that is, and then you can add to it as you go, how would I set the algorithm for that? Can you even algorithm that, and how would you do that if you sell a stock, thus removing one of the numbers, without having to keep a list of every single stock bought?

02:53 <SnoopJeDi> SilverFox, that sounds like a moving average

02:53 <SilverFox> moving average, thank you

02:55 <SilverFox> the variables I have are: number of stocks owned, number to buy, current average, and price to buy at, is this enough for it?

02:57 <SilverFox> im not the strongest at math yet so it's difficult for me to interpret some things

03:00 <SnoopJeDi> the average after N data points: avgN = (p1 + p2 + ... + pN) / N; the average after N+1 data points, where the new price is P: avgP = (p1 + p2 + ... + pN + P) / (N+1) = (p1 + p2 + ... + pN) / (N+1) + P/(N+1) = avgN * N/(N+1) + P/(N+1)

03:01 <SnoopJeDi> i.e. you grab the old terms and write them in terms of the average you already know, then add in the new info

03:01 <SilverFox> thanks, hold up while I try to write this out so I actually understand its process

03:02 <SnoopJeDi> I say it sounds like a moving average because that ^ calculation is for the all-time average, but you probably don't care about all of time, just some window into the past

03:02 <SilverFox> I want all the numbers to be factored in

03:03 <SnoopJeDi> oh okay

03:03 <SilverFox> so if you bought like, 10 stocks, I want the average of those 10 stocks

03:03 <SilverFox> it doesn't matter if they were from 10 years ago or yesterday

03:03 <SilverFox> because the price you bought them at doesn't change

03:03 <SilverFox> the average price is the average of the price you bought the stocks at

03:03 <SilverFox> so if the stock price goes above that average, you are at profit, if it goes below, you are at loss

03:04 <SilverFox> to make the stock buying/selling experience easier for the end user, rather than having to calculate it based on an infinitely long list of stocks and prices

03:05 <SilverFox> so whatever it is that gets me that, I want it, and I need to understand and break it down so I can code it in

03:09 <UmbralRaptop> I want to say that there's some formal term like cost basis or price basis

03:11 <SnoopJeDi> probably both

03:11 <SnoopJeDi> investopedia is useful

05:08 <egg|laptop|egg> !choose dichotomy|bisection

05:08 <galois> egg|laptop|egg: Your options: dichotomy, bisection. My choice: bisection

05:08 <egg|laptop|egg> !choose tetrachotomy|quadrisection

05:08 <galois> egg|laptop|egg: Your options: tetrachotomy, quadrisection. My choice: quadrisection

05:59 <e_14159> SilverFox: That looks like it's achievable by simply storing the sum of prices, and the number of stocks bought. Buying a new one means adding to both, and computing the average price just happens on the fly.

17:04 <galois> SnoopJeDi: rename our bindings after Asimov

17:04 <SnoopJeDi> good bot

17:04 <galois> =]

17:04 <SnoopJeDi> someone (whom I follow on twitter, surprisingly!) is unfortunately squatting `asimov` on PyPI for their thesis, but there are a bunch of other good names from his canon available

17:18 <SnoopJeDi> !or giskard or baley

17:18 <galois> SnoopJeDi: giskard
