Hi thanks for your time, I have a question
Im trying to connect aggr to aggr-server I have running both in Windows
Screenshot_2

I created .env.local in aggr root folder but
Screenshot_3

But im not sure what your say about this parameters

Screenshot_4

Can you provide examples of this configuration. Thanks very much by your time

icazaji commented

how do you know aggr is connected to the aggr-server

Tucsky commented

I see you don't have influxdb on the server side

InfluxDB 1.8 is required for serving preformatted data into a set of timeframe on demand

- Download and run influx

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.10_windows_amd64.zip -UseBasicParsing -OutFile influxdb-1.8.10_windows_amd64.zip
Expand-Archive .\influxdb-1.8.10_windows_amd64.zip -DestinationPath 'C:\Program Files\InfluxData\influxdb\'

or with docker -> https://hub.docker.com/_/influxdb

you can check that influx is running by navigating to http://localhost:8086/query

then you should see aggr-server connect to it in the logs

Setting up .env on client

Yours looks ok, maybe you need to specify the timeframes available... not sure
API_URL is the root url of server and shouldn't include anything after the domain:port/

API_URL=http://localhost:3000/
API_SUPPORTED_TIMEFRAMES=10,30,60,180,300,900,1800,3600,7200,14400,21600,28800,86400

Hope that help :)

Thanks for your time, I have runnign the influx DB and aggr-server on windows but getting this message
{"code":"unauthorized","message":"unauthorized access"}
Screenshot_7

I read is related to some token authentication

icazaji commented

sorry I think I installed 2.2 DB im going to try 1.8 version like your link

icazaji commented

I think is working but I suppose I don't have enough data . There is a way to collect old data?
Check the image says no more data

There is a way to collect old data?

no easy way I'm afraid, especially if you don't know much coding

main purpose of aggr-server is collection and storage in real time, mostly because there is no straightfoward way to download this kind of data (incl. buy / sell volume) for free
Some exchange will let you retrieve tick data from their public API, some don't, some will only allow a day, some only allow 100 trade at a time, some will let you download it from a website (ex https://www.binance.com/en-NG/landing/data) etc...

Another way is stealing the data from some other platform, like coinalize, tradingview or if you got an account in a private platform like tradinglite, exochart you can try to reverse engineering their api but yeah don't expect me to help you do that lmao

If you have the raw trades files, you can format & import them using the following tool
importer.zip (all instructions are in importer.js)

thanks for your time, im coder, all the purpose of setting all this environment is:

  1. Understand the code aggr and aggr-server
  2. I want to create a CVD filtered by trades sizes and exchanges
  3. I want to create Open interest graph like the CVD line
  4. I want to create funding graph like CVD line
  5. To do all this I need understand the code and some data.

Base on what you explain I will let run the server-all day to collect data and im going to focus
on learn the code to create the CVD filtered like step 1
thanks very much

icazaji commented

One last questions, how you know the code and the data Do you think it is possible create a CVD filtered by trade sizes?
for example I want a CVD that graph trades from 1 to 10k and other CVD from 10k to 20M usd only Binance Perps
