i've been trawling the forums and getting various answers on the subject historical data.
i'd like to do some backtesting of custom strategies i've written on various instruments (futures and stocks). ideally on tick data but 1 min is fine for now.
I've got a subscription to barchart.com
To do a 1min level backtest of AAPL from 1-jan-2008, I set the test timeframe and run the test however i only get results from the 15-oct-2008. Does anyone know how to sort this out?
I've tried tools->historical data->reload but it hasnt sorted the problem.
For futures, i've gathered from the forum posts that i need to obtain a historical datasource in NT format and import them into a custom symbol
Can anyone recommend a good datasource?
i've seen tickdata.com but would like to know if there are others out there.
I dont mind paying if its a reasonable cost.
I can code up something to convert the data into the correct format if need be.
cheers
