Multiple instruments & event firing order

[tuanhuy]

Hi all,
Correct - all of the Minimum Bars required for each series needs to be satisfied for OnBarUpdate to run your backtest. In the case where historical data is missing for one instrument, you will not see it run until the historical data is available for all.

Hello tuanhuy, and thank you for your question.

all of the Minimum Bars required for each series needs to be satisfied for OnBarUpdate to run your backtest

This is the responsibility of the programmer to check. The strategy will run even if these are not satisfied. However, trades placed before the bars required to trade have passed will be rejected, disabling the strategy, and referencing BarsAgo indexes before there is data to satisfy them will result in runtime log messages that disable your strategy as well.

In the case where historical data is missing for one instrument, you will not see it run until the historical data is available for all.

OnBarUpdate will process for the instruments you do have historical data for. You as a programmer can run a check to see that every member of CurrentBars has at least one bar available if you would like what you said to be true. This check looks like

foreach(int i in CurrentBars)
{
    if (i < 1)
    {
        return;
    }
}
