Fetch klines of multiple symbols about binance-downloader HOT 8 OPEN

Thanks! Good Suggestion.

There is a rate limit of 1200 requests by minute (10000k rows by second), but the app is not requesting in parallel (for now) so it is much slower, so we are fine.

One possible implementation for this is the following:

Turn the --symbol SYMBOL, -s SYMBOL parameter optional and then create another parameter also optional --quantity QUANTITY, -q QUANTITY that gets the total number of coins (default 1) and then get the first QUANTITY symbols on this endpoint https://api.binance.com/api/v1/ticker/24hr

This one is also a good issue @santoshyadav198613

Hi @samuelhei,
How about we specify what symbols we want instead of quantifying?
So we could use --symbols Symbol1 Symbol2 and the default would be the same.
Another question:
with multiple symbols, we will have multiple files, right?
or we should put all symbols in one single file?
for me, the first option is the right answer.
What do you think about?

We can separate by a comma. Check the similar script.

parser.add_argument("-p", "--pairs",        action="store",       dest="pairs",     help="Pair(s) to download (separated by comma).", default="all")
...
pairs =  list(all_currencies.keys()) if args.pairs  == "all" else args.pairs.split(',')
...
    for pair in sorted(pairs):

Yes, @anderson89marques different symbols we can save in different files.

Good idea @kenorb, I will check out the script

I just used bash for now, save below as a .sh file (including the done on the bottom), then run
bash filename.sh
in command line.

#!/bin/bash
CoinList=("BTCUSDT ETHUSDT LTCUSDT BNBUSDT NEOUSDT ETHBTC LTCBTC BNBBTC EOSBTC")
Start="2018/01/01"
End="2018/01/02"
Output="./binance/train/timestamp_symbol_interval"
for coin in $CoinList
do kline-binance --start $Start --end $End $coin 1m
done
