Re: [amibroker] Forex Intraday data Issue!

[Graham <kavemanperth@xxxxxxxxx>]

In the AFL library I ahve placed a code to export intraday data
This is set up for this purpose as I use this code every time there is daylight saving changes
It is set to be able to import back in using the ascii importer. First time just use the wizard to match the data in the files

Export data using the AFL, with timeshift set to +1 hour. (in October/November this becomes -1 because of daylight saving ending)
Have all the tickers in a watchlist so that you can save the full list, and save all your watchlists first
Delete all the tickers from the database.
One thing to remember that when importing from ascii file the symbols will be set for local databse only, so if you use plugin for data (I use QT) importing to watchlist first allows them to connect
Import back all watchlists
Import data using ascii importer
Change the time shift to suit your location

Time shift does work fine you just misunderstood what you need to do.

The key is to: export *OLD* data ONLY using ONE HOUR timeshift, and then put them together with NEW data (without any shift).

(import to new blank database).

 

There is no big issue and no problem. However, I don't do hand-holding - if you are not proficient with file operations

your better bet is to use eSignal or IQFeed - both provide forex data services that save you all the hassle.

Subject: [amibroker] Forex Intraday data Issue!

Thomasz,

 

I've tried many approaches to exporting and them importing the Intraday data without success.

 

The final attempt was to take the data out of the database using the quote editor. It took several steps to get this data to a .csv file where the Time and Date are seperate fields.

 

The import function successfully imported the data.

 

There is still one MAJOR issue. Exporting/Changing the Time Shift/Importing didn't work.

 

When I changed the Time Shift from -8 to -7, the reloaded data still shifted. In other words the Time Shift works on all records regardless of the shift value it was originally loaded with.

 

The problem remains!

 

Bill
