I just tried to open a chart on a forex symbol for the first time and it has been downloading data for the last 10 minutes with no end in site.

The same chart for a future symbol, downloaded the data very quickly.

How can I limit it so that next time I try to open a new forex symbol it won't load hundreds of pages of tick data?

The waiting time has to do with
1. The look back period in days of your chart
2. The type of the chart(min,tick etc)

If you try to open 500days back 1min data... then you wait longer than opening 500days back 240min

Also keep in mind that as you downloading data for more symbols your data folder will get bigger and bigger

From chart settings you can manage the days to load

after reading the advice above, I set the chart "number of days to load" to 1 (it was 30 before)

then I changed the symbol on the chart.

And still it takes forever and I can see it loading many more days than just 1 day of data on the 1M chart.

Any ideas?

Hello ycomp

Yes it doesn't make sense...imagine that 30 days intraday chart with 1tick data should download pretty quick.

Is it a historical or intraday chart?

what is the symbol by the way?

Intraday EURJPY.. the first post was about EURUSD.. both loading for the first time.. but with EURJPY I specifically changed it to 1 days to load on chart settings, and it took about 15 minutes.. I would see pages and pages of hours scrolling by.. so individual days looked like they were loading fairly quickly - just many many days of data was loading.

Seems I can scroll back now to may 20th.

Very strange, anyhow I guess there would be no way for anyone here really to know what is going on. Guess I have to play with it some more.

If you don't mind what broker you use?

I meant you downloading data via broker or from Sierra data feed directly?

it is CQG demo but I think that means it uses FXCM data from SC for forex pairs

I don't seem to have this problem on other currencies anymore but I made sure to change the historical look back on all charts for the current pair in the chartbook, even though they are not linked in anyway before switching them to a new pair

Since there is no "real" volume data for FX pairs there is really no reason to store tick data.

Go to Global Settings > Data/Trade Service Settings and change 'Intraday Data Storage Time Unit' to the lowest tolerable resolution. Your charts will load much faster if you store as multiple seconds or minutes instead of ticks.

Thanks to future.io policies I can't post a link to the documentation but you should read it. It's very thorough.

I need Tick data to make my tick charts though

there might not be "real volume" but it is highly correlated when it is from a good source like FXCM.. some random broker though might be a different story. But FXCM data is even used by some of those expensive data feed sellers.
