Is it possible to export market data for years at a time?
It seems like you can only do it per contract, meaning you’d have to do 4 exports per year. Given you can backtest for years at a time I would have thought you could also do a continuous export.
You can download a lot of data at once.
I took MNQ09-25 and asked data for 1000 days.
I then used the indicator charttoCSV and a few seconds later I got an excel with data from 2022 till today.
I took daily data. If you need smaller timeframes ( hours, minutes or ticks) it is possible that the historical data is not available for such a long period. It will also export all indicator values that you have in the chart.
Just try it.
Keep in mind that the older contracts are adjusted to the latest contract, so you don’t get original values.
