I'm trying to run ShowAccount.ipynb, so I cloned the repo and did pip install requirements.txt which worked fine.

I'm now trying to run the second cell and I get the following error: ModuleNotFoundError: No module named 'solana.keypair'

Has this dependency been missed from requirements.txt or am I making incorrect use of this repo?

I would like to use the PR as a manner to discuss a trouble when I want to use different ports for HTTP(S) and WS(S) connections. Currently the cluster_urls can be configured as https and then the protocol is switched for wss when websocket subscription is created : https://github.com/blockworks-foundation/mango-explorer/blob/main/mango/websocketsubscription.py#L62

What I would need is having chance to define different protocol https vs. ws and/or different port for WS and HTTP connections.

I'm thinking about changes in code. (The currently proposed ones neither work fully nor are clean for being good to be merged.)

I was thinking to have instead of cluster_urls: typing.Sequence[str] a dictionary like cluster_urls: typing.Dict[str,str] where would be possible to say cluster_urls = {'https': 'https://localhost:8080', 'ws': 'ws://localhost:8181'}. But this kind of change is more difficult to place to be loaded from command line args (or maybe not and I just need to find how to do it). I took kind of side step here in way to represent the issue.

If such kind of change would be desirable then I would fix and clean the proposed code in way that will be recommended to me. If such kind of change is not a thing that should be part of this codebase I will delete this PR.

Thank you for any feedback.

It was working last Friday, but throwing exceptions today on devnet. It still works on mainnet.

Once installed, and run :

• I got security warnings over Ghostscript dev right
• Once i bypassed this warnings in my own conf, and run an example script, i found... A screenshot of my shell appeared in the working directory !

I've installed it with pip3, with your source. What's going on ?

Hi all. I'm a Python programmer and a cryptocurrency trader. I would like to get current orderbooks of any symbol in Mango Markets for trading. If you can, please give me some example. Thank you, your countribution.

It seems that the top-bids are wrongly calculated when updated by watchers.

Based on the comments and code https://github.com/blockworks-foundation/mango-explorer/blob/v3.2.8/mango/orders.py#L238 the top-bid should be at index 0. That's to reverse the order of the list. That's what the init function in OrderBook does. That's what is not done when updated in watchers https://github.com/blockworks-foundation/mango-explorer/blob/v3.2.8/mango/watchers.py#L224 the order reverse is not processed and the top-bid then returns the bid at tail.

Not sure if reversed is correctly used at pandas dataframe creation - https://github.com/blockworks-foundation/mango-explorer/blob/v3.2.8/mango/orders.py#L284

Great writeup on how to run a liquidator. However, when I get to the dry run for running the liquidator I got the following exception and the liquidator terminates.

Exception: Account 'Dd8sgey2VD1uo5jBJfwJAdfi2GZAvULcoSqAy87jQGBT' is not prepared for group '2oogpTYm1sp6LPZAWD3bp2wsFpnV2kXL1s52yyFhW5vp'.

Any ideas?

We do experience a trouble when HTTP request is stuck. The mango explorer market maker is then hanging forever at the requests.post call. The expected processing is that the request is timeouted and processing switches to the next node in the list. This PR proposes a change bringing such a behavior.

@OpinionatedGeek WDYT?

The existing example is not functional, due to the change from load_orders -> load_orderbook in this commit.

This changeset amends the example to be functional, with a small modification to place the order at a value we'd typically expect to see in the orderbook representation rather than a fixed $ value, which is hopefully a bit easier for a first time user to understand when they can see their order in the orderbook.

I have kept the print convention of the existing example, but please let me know if you would prefer it be changed to a Python 3.7-esque syntax with f-strings etc.

There is a missing way to configure the max retries on sending transaction to RPC node. The attempt of this PR is to fix this deficiency. What do you think @OpinionatedGeek ?

>>> sl.net_value
« InstrumentValue:        -0.00040000 BTC »
>>> sl.perp_account.base_token_value
« InstrumentValue:       400.00000000 BTC »
>>> sl.perp_account.base_position_raw
Decimal('400')

Instrument value of perp base token position is shown in raw. Should convert by decimal.

Hi I tried to install mango-explorer via pip. We got an error

ERROR: Could not find a version that satisfies the requirement mango-explorer (from versions: none)

Hello team,

I've been going through the sdk, but can't seem to find how to get the average entry price for a perpetual position.

Can someone let me know what's the way to do that?

Thanks
