Binance Futures - Change Leverage (Python)

I’m not able to change the leverage with the “fapiPrivate_post_leverage” function. Can someone help me?

• OS: Windows 10 x64
• Programming Language version: Python 3.8.2
• CCXT version: 1.28.3

Code:

import ccxt

binance = ccxt.binance({
    "options": {"defaultType": "future"},
    "timeout": 30000,
    "apiKey":"xxx",
    "secret": "xxx",
    "enableRateLimit": True,
})

binance.fapiPrivate_post_leverage("BTC/USDT", 10)

Error message:

TypeError: inner() takes from 1 to 2 positional arguments but 3 were given

Hi!

Please, see:

1. how unified ccxt symbols differ from exchange-specific market ids: https://github.com/ccxt/ccxt/wiki/Manual#symbols-and-market-ids
2. how implicit API endpoints are called: https://github.com/ccxt/ccxt/wiki/Manual#implicit-api-methods

You should pass an object containing the params, instead of supplying the params as arguments:

import ccxt

binance = ccxt.binance({
    "options": {"defaultType": "future"},
    "timeout": 30000,
    "apiKey":"xxx",
    "secret": "xxx",
    "enableRateLimit": True,
})

binance.load_markets()  # load markets to get the market id from a unified symbol
market = binance.markets['BTC/USDT']
binance.fapiPrivate_post_leverage({
    "symbol": market['id'],  # convert a unified CCXT symbol to an exchange-specific market id
    # "symbol": "BTCUSDT",  # same thing, note there's no slash in the exchange-specific id
    "leverage": 10,
})

Let us know if the above does not help.

@bluesme519 if one call to set the leverage works, and then the other call fails, then please, post the request+response for both calls:

    binance.enableRateLimit = True

    binance.load_markets()  # load markets to get the market id from a unified symbol
    
    binance.verbose = True
    
    market = binance.markets['BTC/USDT']
    
    binance.fapiPrivate_post_leverage({
        "symbol": market['id'],  # convert a unified CCXT symbol to an exchange-specific market id
        # "symbol": "BTCUSDT",  # same thing, note there's no slash in the exchange-specific id
        "leverage": 3,
    })
    
    binance.fapiPrivate_post_leverage({
        # "symbol": market['id'],  # convert a unified CCXT symbol to an exchange-specific market id
        "symbol": "BTCUSDT",  # same thing, note there's no slash in the exchange-specific id
        "leverage": 3,
    })

If the above works, that means you’re violating this part of the Manual: https://github.com/ccxt/ccxt/wiki/Manual#notes-on-rate-limiter

If every call to set the leverage fails for you, i’d recommend contacting Binance tech support, since it may be that Cloudflare flagged your IP (try from a different location to rule that out) or it could be related to a flag on your account. In both those cases only Binance can really help resolve it.

The code I made was reusing the same instance over and over again. I need to change it to reduce burdens of binance api server. Thank you so much for your guidance for all bunch of stuffs!!
