I was previously using quantsrat_0.9.1739 & blotter_0.9.1741 for some time and it worked fine until I updated them to the latest version 0.10.7 with blotter 0.12.4.
Most of the simulations that I previously wrote throw in the following message: (This one has been extracted from the demo(macd))
Warning message:
In .updatePosPL(Portfolio = pname, Symbol = as.character(symbol), :
Could not parse ::2018-01-12 as ISO8601 string, or one/bothends of the range were outside the available prices: 2007-01-03/2014-05-30. Using all data instead.
It modifies the end results of nearly 50% of the backtest I generated in the past. If I go back to the previous version of quantstrat and run the same strategies everything goes back to normal.
I would appreciate if anyone who might have faced the same situation as me could let me know how this problem can be fixed.
Here is more info regarding my session:
