Hey,

I previously used both the Binance and Coinbase plugins to fetch both M1 and EOD data directly through Zorro.

However, I'm having issues doing the same through the Kraken one which I plan to use due to its support for SET_LEVERAGE.

I'm wondering what I'm doing wrong with this script:

Code

function main() 
{
	
	
	StartDate = 2021;
	EndDate = 2022;
	Verbose = 7|DIAG;

	assetHistory("ETH/USD",1);
	
}

getting the following output

Code

Any thoughts on what went wrong?

Either way, I explicitely set the symbol too, but still getting errors. To me it seems that the internal pagination logic of the plugin may be broken, as seen in the log.

There's prob a limit on the number of data queries, which is pretty common for most sources. Last edited by Grant; 03/07/22 12:41.

To avoid bans, SET_DELAY was preconfigured to sufficiently slow responses. SET_DELAY affects all REST requests, but no open websocket streams. was wondering if anyone knows a reliable way to circumvent this - maybe a value to use with SET_DELAY

If the rate limits are reached, additional calls would be restricted for a few seconds (or possibly longer if calls continue to be made while the rate limits are active). Code function run() { set(PLOTNOW,LOGFILE); BarPeriod = 1; StartDate = 20220101; brokerCommand(SET_DELAY, 10000); asset("ETH/USD"); if (is(INITRUN)) { assetHistory("ETH/USD", 1+OVERRIDE); } } Last edited by loopiezlol; 04/03/22 12:49.
