Could not download history candles
Could not download history candles

I tried multiple times to download last 10 historic candles calculated from given date for different Periods(H4, H1, M30) and Instruments(EURGBP, EURCAD, XNGUSD) but api didnt return to me with actual data after 10 seconds. After 30 minutes I retried to download them and it was a success. This happens on average once per month. What is the issue? Maybe I`m doing something wrong?

@PanagiotisChar I found more info about issue. We did actualy get the date but it was after waiting around 8 minutes for it. Normally it works very fast we get data in matter of seconds but ocasionally we wait like 8 minutes. Is it a bug or thats the design?

Sounds like none of the two. Such issues can occasionally when you work over the internet

Its not the case of internet. I didn`t lose connection with api. In this 9 minutes period I was still receiving messages like: PROTO_OA_SPOT_EVENT. If my program wont get candles within 30 seconds it sends again message with request for candles few times. Even for these new requests it had to wait around 9 minutes.
Is it possible that If I subscribed for message PROTO_OA_SPOT_EVENT its delaying message PROTO_OA_GET_TRENDBARS_RES ?

It's not only about your connection to the internet but the entire route to the server. Something can happen on between and packages can be lost

I understand that, it can happen. If within 30 seconds I dont get any response I send request again and again and again. Within 9 minutes Ive sent more than 10 requests to get candles and still I couldnt get response within reasonable time. What I can do to fix issue as I cannot wait 9 minutes for candles.
