Historical values

[laresbernardo]

Hi Marcos! Thanks for sharing this awesome tool/code with us. Do you think it could be possible to fetch historical results so we can compare min, med, max values in a range of dates? Thanks again!!

Hi @laresbernardo! Nice to get in touch! At the moment I could not find a public binance API with the p2p logs.

I see two options of how we could add this feature:

1. Saving the results of each query in a local db or in json format on disk. It is partially useful and a cronjob could be added.
2. Use a public cloud to save the results of the queries of each Binancio user. (e.g. Firebase, MongoDB Atlas) I find it interesting as an experiment, but it would be exposed to attacks and inaccurate information.

I will see if I can think of any other option, any suggestion is welcome! Thanks for the feedback.

Thanks!! I'm looking for a way to analize the distribution of daily P2P transactions (currency / USDT) vs the official exchange rate. Looking closer at your code, I noticed you added ARS as default (so you must from Argentina). For our LATAM countries, we have crazy things happening in our economy (I'm Venezuelan, lived in Argentina until a couple of months ago, and am in Colombia now)... and having this trends are quite valuable to time buying/selling correctly. Hopefully, you can help me come up with a solution no getting this data! 👍

¡Es un placer enorme estar en contacto con un hermano venezolano! You are right! I'm from Argentina and I totally understand your point! 💸

In my case, I had already tracked the cryptocurrencies and their price in USDT and I needed to calculate the median in local currency to be clear about how my investment was performing, this is where Binancio was born.

What I did was set up a local MongoDB collection and a cronjob that saves the USDT @ ARS output generating a historical record every N times a day. Then I can see the historical analysis in my DeFi dashboard with graphs and setup alerts to take advantage of certain opportunities and to avoid certain risks.

To get the price of any cryptocurrency against USDT, try consuming this Binance API: https://www.binance.com/bapi/asset/v2/public/asset-service/product/get-products?includeEtf=true

p.s: If I have time on the weekend I will add a parameter so that the output is just a json, maybe useful for your case. Let me know if you think I can help you. Thanks!

That's great @sanchezmarcos . Thanks for taking the time!

• I've noticed you also had some issues scrapping the data. I couldn't replicate your request shared in StackOverFlow (left a comment there 3 days ago) running the same code in Python.
• Trying to use the https://p2p.binance.com/bapi/c2c/v2/friendly/c2c/adv/search API, I'm adding ?asset=USDT&tradeType=BUY&fiat=COP manually but no results either. Any idea where is the documentation for that bapi/c2c... API? It seems it has what I need but I can't seem to get it right.
• I successfully connected with my API credentials to other documented Binance APIs, but nothing on P2P.
• And having bapi/asset/v2/public/asset-service/product/get-products?includeEtf=true results is great but 1. doesn't havee historical values and 2. doesn't have actual P2P transactions (which is exactly what I need) exchanging cryptos (USDT...) for fiat (ARS/COP/...). Actually, your tool shows open "ads" but not actual transactions, right? I guess they're much better as they are "real" values.
