So in there's obviously a limit in backtesting start date, and in tick-mode the backtesting avalable period seems to be shorter than if we backtest with 1m bars.
So my question is. In tick-mode, does the the date that I can start my backtesting from moves forward with tome. E.g., in 2019 we won;t be able to backtest the 2014, right?
The answer to your question is no the backtesting data start date is not moving forward with time. The availabilty of backtesting tick and trend bar data is related to the amount of availability historical data provided by your broker.
