Ok I just found why I had an empty array, it seems that params order is dateEnd then dateStart like you did.
But the documentation of bitsharesjs-ws is :
https://github.com/bitshares/bitsharesjs-ws

Quote
get_trade_history   [string base, string quote, date start, date stop, int limit]



Thanks

Keep in mind that repo and documentation is few months out-of-date :)))

This is a query that returns a result for me:

{"method": "call", "params": [0, "get_trade_history", ["BTS", "USD", "2018-12-17T16:13:49", "2018-12-16T16:13:49", 10]], "jsonrpc": "2.0", "id": 3}

It requires the market_plugin to be enabled on the backend. Try against "wss://node.bitshares.eu"

Great, it works, thank you.

But I don't know why I have an empty array as result for :

Code: [Select]
Apis.instance().db_api().exec( "get_trade_history", [ "BTS","USD","2018-12-16T15:09:11","2018-12-17T15:09:11",100 ] );

Try this format:

2018-12-17T15:00:00

note that **T** in the middle

Hi,
I would like to retrieve market history.
I'm trying with  :

Code: [Select]
Apis.instance().db_api().exec( "get_trade_history", [ base,quote,dateStart,dateEnd, 100 ] );
But i got an error :
Quote
basic_string::at: __n (which is 0) >= this->size() (which is 0): basic_string::at: __n (which is 0) >= this->size() (which is 0): unable to convert ISO-formatted string to fc::time_point_sec


Here is dateStart and dateEnd format :

Someone can help me please ?

 Is there a better way to get history price for a chart, may be an OHLC format ?
