Hi, I'm trying to create series for differences between current DayOpenPrice and close of prices from other timeframe (ex. hour). Unfortunately my code generates mentioned error. Maybe I don't understand something?


var* PriceDiff = series(abs(priceClose(0)-dayOpen(UTC, 0)));

The stock exchange normally opens at 9 so ýou can not know the open of the day when you call that function in a morning bar. Only in a later bar you can know the open of the day. Hope I made sense?

Yes it's true, I've made few mistakes here. First of all - dayOpen refers to stock open (9 to 4) and it won't work properly in fx market, second - I shouldn't call priceClose with index, third priceClose can fill series, dayOpen obviously not.

The first assumption is correct, so when you trade forex only, you need not use dayOpen.

Aside from that, your above code is ok - you only must take care not to request prices that lie in the future. So use the Open of the previous day only - dayOpen(UTC,1) - when the current bar has a local time before 9:30.
