QUESTION
Does anyone know what before
and after
in Coinbase Pro's trades api (url here) correspond to? I have tried linux epoch but that didn't work.
ANSWER
Answered 2022-Mar-29 at 06:29In all honesty, I automatically assumed the before
& after
parameters were intended to be epoch timestamps like you. After reading back through the exchange/cloud docs I realize it's actually a method to incorporate cursor pagination sending REST API requests to the Coinbase API.
Cursor pagination is the most efficient way of navigating through large amounts of ordered data one chunk at a time. When you consider how many real-time data points and historical data point Coinbase possesses, it makes sense why you would only want to get the small amount of data that's relevant to you or the user at any given time.
Here is what the docs say about pagination when using their API:
Coinbase Exchange uses cursor pagination for all REST requests which return arrays.
Cursor pagination allows for fetching results before and after the current page of results and is well suited for realtime data. Endpoints like
/trades
,/fills
,/orders
, return the latest items by default. To retrieve more results subsequent requests should specify which direction to paginate based on the data previously returned.
I suggest you take a quick look at the page in the docs that is dedicated to cursor pagination. It offer a concise explanation of a somewhat complex topic.

QUESTION
I am going to work on a project in which we want to build a bitcoin wallet, like for example mycelium, coinbase etc, but I have no knowledge of which apis we should use to connect directly to the bitcoin blockchain 1could you give me recommendations for documentation on this. Thanks
...ANSWER
Answered 2022-Mar-14 at 14:39This way you will understand how you can create an app (wallet) that generates Bitcoin addresses.
Wallet and public address are different things: a wallet is an application that creates and stores private keys and makes the public key available as the crypto address where the coins will be received.
Note that the steps are incremental. The next step always has the copy of the previous step.
QUESTION
I'm trying to check if my webhook works, and will implement it. So that I can receive notification when charge is confirmed (charge:confirmed)
So I created php code to check my webhook,
...ANSWER
Answered 2022-Mar-06 at 05:21I was able to solve this,
Just in case you are here. Please create an API Endpoint on your project using POST
method with
X-Cc-Webhook-Signature
equivalent to your Shared API Secret Key
User-Agent
currently I'm using weipay-webhooks
(as per documentation)
and submit your json data for checkout
On my end I used postman to test my api end point.
Your PHP Code must accept X-Cc-Webhook-Signature
and automatically the coinbase commerce will use your webhook link when someone purchased.

QUESTION
I found this script on tradingview.com when they announced "Our new alerts allow for dynamic messages." The script is supposed to trigger an alert when RSI is overbought or oversold. The problem is it does not work as intended. The alert is triggered by the RSI for which symbol you added. It appears to select at random the symbols in the symbol list at the bottom of the script. The RSI data along with the script is also Incorrect as it is sending the RSI of the symbol you originally added the study to, not the RSI of the symbol list.
Here's the alert text to show nn example of the error:
"NASDAQ:AMD, 1: RSI (50.5282994084) crossing up 70 level" alert() with multiple symbols: any (alert) function call Active NASDAQ:AMD, 1m" This doesn't make sense since the RSI of AMD did not cross over 70 at the time the alert was triggered and it shows the RSI was 50, but it wasn't even 50 at the time of the alert it was under 30.
I tried moving the "_r = rsi (close, 7)" under the "[_co, _cu]..." line, but it did not work. I also tried to convert the data to strings to see if that did anything, but it didn't work. I tried converting to Pine Script v5. Also tried different symbols and crypto. Does anyone know if this function of applying an indicator/study to multiple symbols at the same time actually works? Or, perhaps I'm missing something and it's not working because of something I'm doing wrong.

Answered 2022-Feb-22 at 21:54I think what you expect the array to look like and what it actually looks like are different. $json['USD']

You can use print_r
on the array to view it:
