Warnings and Failed Date Ranges in Backtest

  I am getting a lot of failed attempts when I change date ranges since using the new V10.3 Backtest date ranges window? Please see screenshot.

  Is anyone else getting this? The solution seems to be to changing the dates to something else and then back to the desired range.

  I’m also seeing this warning when a strategy is open in the background (and being used an daily chart) but I go to change the number of units on a completely different chart (10 min chart)?

  When this warning window appear, I always close the Probacktest window and open it again with the desired chart for backtest.

  I would but I’m getting this every session, plus it takes a while to load up the 8 charts two with 5 MESA indicators. Strange though as I never had this issue with v10.2?

  Hi Dref … you’re missing an IF and Endif … see below.

  However you’ve hijacked Bard’s Thread so best not to reply (raise your own Thread?)

  I just got the date range warning when changing a Dow chart from 10,000 units to 200 units? What is causing this? Never had this with v10.2 !

  Hi Nicolas,

  Do you know if it is possible to get a permanent code fix on the continuing date range issues in V10.3?

  I did try your suggestion and closed PRT and relaunched it today. It makes no difference and makes backtesting difficult. (Note: These errors were rare in V10.2 and easily resolved by changing date parameters and then going back to the original range choice).

  Thanks

  Hi all I also get this error message whenever I try to backtest on a specific date range. Is there a particular sequence or workaround for this? Currently I only back test on units for the 1 minute time frame then have to manually scroll back to the date that I wish to look at which isn’t ideal. Thanks in advance.

  It can happen when you try to backtest a time range period which is not displayed in your chart. The quick work around is to display the maximum units possible for your trading account type (max is 100.000 bars with IG v10.3) or to close the chart and your code and re-open them again and restart the process to get the right backtest period.
