How this work?

[aquinary]

I'm sorry if I'm asking obvious questions. But it's hard for me to understand why I observe different behavior where it shouldn't be (or I don't understand it). All results will be based on this request to the Swagger API:

https://west.albion-online-data.com/api/v2/stats/Charts/QUESTITEM_EXP_TOKEN_D4_T6_EXP_HRD_HERETIC_FISHYBUSINESS.json?date=2023-12-13&qualities=1&time-scale=24

The date will change, which I will not forget to specify.

1. I use the value 2023-12-13 as the date and get the following result:

   [
   {
   "data": {
     "timestamps": [
       "2023-12-12T00:00:00",
       "2023-12-13T00:00:00"
     ],
     "prices_avg": [
       14422,
       14431
     ],
     "item_count": [
       2,
       3
     ]
   },
   "location": "Thetford",
   "item_id": "QUESTITEM_EXP_TOKEN_D4_T6_EXP_HRD_HERETIC_FISHYBUSINESS",
   "quality": 1
   }
   ]

   Why do I see data for 2023-12-12T00:00:00?

2. I use 2023-12-12:

   [
   {
   "data": {
     "timestamps": [
       "2023-12-11T00:00:00",
       "2023-12-12T00:00:00",
       "2023-12-13T00:00:00"
     ],
     "prices_avg": [
       14339,
       15438,
       14431
     ],
     "item_count": [
       2,
       8,
       3
     ]
   },
   "location": "Thetford",
   "item_id": "QUESTITEM_EXP_TOKEN_D4_T6_EXP_HRD_HERETIC_FISHYBUSINESS",
   "quality": 1
   }
   ]

   Why is the value for 2023-12-12 different in both cases? 14422 vs 15438? When I write 2023-12-12, do I get data for the whole day or some data selected in the middle of the day?

3. I use 2023-12-11:

   [
   {
   "data": {
     "timestamps": [
       "2023-12-11T00:00:00",
       "2023-12-12T00:00:00",
       "2023-12-13T00:00:00"
     ],
     "prices_avg": [
       16317,
       15438,
       14431
     ],
     "item_count": [
       11,
       8,
       3
     ]
   },
   "location": "Thetford",
   "item_id": "QUESTITEM_EXP_TOKEN_D4_T6_EXP_HRD_HERETIC_FISHYBUSINESS",
   "quality": 1
   }
   ]

   Why don't I see information for 2023-12-10 now? (this information exists, I checked). In the first two paragraphs, I received data for a day ago, but in the third paragraph, this is not the case. How does it work?

4. I make new request:

   https://west.albion-online-data.com/api/v2/stats/Charts/T4_METALBAR.json?locations=Caerleon%2CBlack%20Market&date=2023-12-12&qualities=1&time-scale=24

   Get result:

   [
   {
   "data": {
     "timestamps": [
       "2023-12-11T00:00:00",
       "2023-12-12T00:00:00"
     ],
     "prices_avg": [
       206,
       220
     ],
     "item_count": [
       40346,
       9758
     ]
   },
   "location": "Black Market",
   "item_id": "T4_METALBAR",
   "quality": 1
   },
   {
   "data": {
     "timestamps": [
       "2023-12-11T00:00:00",
       "2023-12-12T00:00:00",
       "2023-12-13T00:00:00",
       "2023-12-14T00:00:00",
       "2023-12-15T00:00:00"
     ],
     "prices_avg": [
       206,
       220,
       178,
       177,
       169
     ],
     "item_count": [
       40346,
       80896,
       105927,
       73705,
       73937
     ]
   },
   "location": "Caerleon",
   "item_id": "T4_METALBAR",
   "quality": 1
   }
   ]

How can T4_METALBAR have a price on the Black Market? Why is it identical to Caerleon prices? (and there are quite a lot of such positions).

Perhaps I don't understand something. I will be glad if someone explains to me how it works :)

Is this an albion price problem or ao data?
