Cannot get DAY_OPEN_MID from REST API

[SCROTCH]

Hi

Using the streaming API, it's possible to get DAY_OPEN_MID for the current trading session using a CHART:TICK subscription. The same value can also be obtained from MID_OPEN using a MARKET subscription. Lastly, it can also be calculated for the current trading session using the /markets endpoint of the REST API using the "bid", "offer" and "netChange" attributes.

Note that all of these options apply to the current trading session only, and there doesn't seem to be any way to fetch or calculate the same value for previous sessions. I would like this info as part of my backtesting strategy. Is there any way to fetch or calculate it using the REST API?

Hi,

Get the price history. This will give you the candle opening bid/ask, then find the mid point.

'https://api.ig.com/gateway/deal/prices/'+epic+'?resolution='+freq+'&from='+d1+'&to='+d2+'&pageSize='+str(5000)

 

You need to add epic, freq, d1, d2

Hi

Thanks for responding but I should have made clear that it's impossible to determine the Monday morning gap up/down from the candle data.

eg DAY_OPEN_MID on Monday for IX.D.DOW.IFA.IP was 30195.4 whereas the candle from the open returns 

"openPrice": {
    "bid": 30401.5,
    "ask": 30406.3,
    "lastTraded": null
}
