add rate limiting to ccxt.

Features

• Rate limit per endpoint

Install

pip install "git+https://github.com/richmanbtc/ccxt_rate_limiter.git@v0.0.6#egg=ccxt_rate_limiter"

Usage

Create RateLimiterGroup

• RateLimiterGroup handles rate limiting by tags.

from ccxt_rate_limiter import scale_limits
from ccxt_rate_limiter.bybit import bybit_limits
from ccxt_rate_limiter.rate_limiter_group import RateLimiterGroup

limits = bybit_limits()
limits = scale_limits(limits, 0.75) # Multiply the rate limit value by a certain magnification to allow a margin.
rate_limiter_group = RateLimiterGroup(limits=limits)

Wrap ccxt instance methods to call RateLimiterGroup before api call

• RateLimiterGroup can be shared between multiple ccxt instances.
• RateLimiterGroup can be shared between multiple threads (thread-safe).

import ccxt
from ccxt_rate_limiter import wrap_object
from ccxt_rate_limiter.bybit import bybit_wrap_defs

bybit = ccxt.bybit({
    'enableRateLimit': False, # disable built-in rate limiter
})

wrap_object(bybit, rate_limiter_group=rate_limiter_group, wrap_defs=bybit_wrap_defs())

Call api

bybit.publicGetTickers()

# rate limiter status
print(rate_limiter_group.status_info())

How to customize rate limiting

Custom rate limiting settings can be used.
