Hello Gius, I'm trying to work with the library for python, and I'm searching for the method that gives me the opportunity to retrieve the amount in EURO inside my account. In other words, I need to query how money is ready on the exchange to trade. Thanks

Hey, I was wondering how one can get the error type when ccxt throws.
do I have to manually check the error class ? It's a pain

Like, do I have to do this ?

          if (e instanceof ccxt.InsufficientFunds) {
            error = 'InsufficientFunds';
          }
          if (e instanceof ccxt.OrderNotFillable) {
            error = 'OrderNotFillable';
          }

etc...

@pavs94 see this issue: ccxt/ccxt#4341

@Antonhansel in JS there's no other way of checking the error type, but you can also get a string name like so:

try {
} catch (e) {
    console.log (e.constructor.name)
}

@yegito2_twitter yes, it does support futures orders to a certain extent, most of it is covered in the existing issues on github as well as the examples

Hi! I found this board searching for a solution in resetting nonce to use same API key wits several instances of my python script. I know as stated https://github.com/ccxt/ccxt/wiki/Manual#authentication I shouldn't use same pair with several istances of my script , but for some reasons I have to. So I used the override nonce https://github.com/ccxt/ccxt/wiki/Manual#invalid-nonce but isn't work. Any suggestion?

Hi guys a quick question, how is idempotency normally ensured for order placement? APIs such as Stripe offer idempotency keys which can be included in the header to ensure the same operation is not executed twice. I am trying to find a similar mechanism for crypto exchanges and not having any luck.

I thought that ClOrdId could serve as such a key but e.g. Okex doesn't give a shit if you have just executed an order with the exact same ClOrdId and places another order when ClOrdId is repeated

Oh I see, this chat is dead

Hi there @kroitor and team

hope all is well

I have been getting these two types or errors:

ERR_LIMIT
Unexpected Error Code: 429

could you please confirm if and whether these relate to (LIMITS) and what those (LIMITS) are? I understood the limits are not enforced (especially since my app is still in testing / development mode)

I am happy to increase my subscription if I'm given guarantees that it will solve my issue (I'm using data from 6 exchanges only)

thanks!

Hello there, can anyone suggest a cheap web hosting provider that can run PHP version of CCXT? On the host I am using, I am getting an error that GMP extension is not available. The hosting has the option to change to PHP v7.2 and v8.0 but it still doesn't work with those. They don't want to help me fix it.

Hi guys, I'm new here. I have a big problem with the ccxt api. I'm writing here because I think that it is not a lib error, instead, it could be my error or exchange error, so.... this is my problem:
I'm using python and I wrote a sort of bot that calls something like 120 http requests per minute and in some particular cases, it could be 130/140 requests per minute. Anyway, the bot work, and it works great, but after 12h/24h it breaks for this error:

The above exception was the direct cause of the following exception:

I tried different solutions:
1- repeat the request after 1 second for 5 times
2- increase the timeout

repeat the request after x + 1 second after x time of retry with a maximum retry of 5

All of that doesn't work. Can someone explain to me why this error?
