SpinnyBobos suggestion of using OnMarketData seems to be the way to go, unless you need to backtest.

Just curious why do you not want to use CalcOnBarClose = false ?

Thanks.

for me, using OnBarClose = false becomes problematic when you need values for each bar from things.

I don't know how it is with using indicators like SMA or stochastics and stuff, but if you use

Code

protected override void Initialize()
{
      CalculateOnBarClose = false;
}
protected override void OnBarUpdate()
{
    if (FirstTickOfBar)
    {
         if (Close[0] > someValue)
           // do something
    }
}

Unless there is a different way that I don't know about, I am thinking this is how you would normally get around using OnBarClose = false through using FirstTickOfBar

When you compare using the same exact logic with

Code

protected override void Initialize()
{
      CalculateOnBarClose = true;
}
protected override void OnBarUpdate()
{
     if (Close[0] > someValue)
        // do something
}

they don't always give the same values. Therefore if your strategy is heavily reliant on things being exact with data values, then it makes sense to use OnBarClose = true

If you have to backtest something, just

Add(PeriodType.Tick, 1); // to Initialize()

just make sure you download the data first before you load the chart so it does not take forever to load.

Yes, definitely looks timing related (FirstTickOfBar vs OnBarClose), as Close[0] changes with every tick. I will keep that in mind, but for now I have given up on NT, as support couldn't answer my questions on unmanaged strategies. The big issue is they have no Order.Close function like every other trading language I''ve used. And the only strategy they could point me to as an example is CamarillaPointsUnmanaged. One, when ran in real mode it bombs with an order reject. And two, it stops out or hits profit target. That's the only way to get out of the order.

If I missed something, I would love to know how to close an order. I entered a reverse BuyToCover or Sell to get out and sometimes it works, and sometimes it opens up new positions.

Thanks.
