How to exit long and enter short the same bar

I believe it should be a common case, but I couldn't find it in the Discussions.

I have a simple reverse strategy in code:

CODE:

if (HasOpenPosition(bars, PositionType.Long) || HasOpenPosition(bars, PositionType.Short))
{
   //Check and exit if needed
   ClosePosition(LastPosition, OrderType.Market, 0);
}

if (!HasOpenPosition(bars, PositionType.Long) && !HasOpenPosition(bars, PositionType.Short))
{
   // Check and enter if needed
   Transaction  t = PlaceTrade(bars, TransactionType.Short / Long, OrderType.MarketClose, 0, "Short");
}

This code exits (long) on one bar, and enters short (if criteria is still met) next bar.

I need to close long and open short at the same first bar, but I don't see a way to understand that the long position is closed, and HasOpenPosition returns true until the next bar.

Can you please suggest any way to make the strategy truly reverse?

Thank you

You couldn't find answer in Discussion probably because this is more a "reversal strategy" than a "same bar exit" question. Check out Cone's post 8 in topic below for the answer:

So with regard to the provided link I should have my code modified as follows:

CODE:
if (HasOpenPosition(bars, PositionType.Long) || HasOpenPosition(bars, PositionType.Short))
{
   //Check and exit if needed
   ClosePosition(LastPosition, OrderType.Market, 0);
   // Check and enter if needed
   Transaction  t = PlaceTrade(bars, TransactionType.Short / Long, OrderType.MarketClose, 0, "Short");
}

if (!HasOpenPosition(bars, PositionType.Long) && !HasOpenPosition(bars, PositionType.Short))
{
   // Check and enter if needed
   Transaction  t = PlaceTrade(bars, TransactionType.Short / Long, OrderType.MarketClose, 0, "Short");
}

Seems to work fine. Thank you, Eugene!
