I am trying to create a trading strategy that swaps between long positions in two symbols based upon a signal. When the signal is positive, the strategy should sell the long position in symbol A and take a long position in symbol B. When the signal is negative, the strategy should sell the long position in symbol B and take a long position in symbol A.

I have created a system that I thought should accomplish this, but it does not always take the long position in stock A when it sells stock B and vice versa.

My code is shown below. Any help would be appreciated.

By looking at the familiar lines at the beginning of your code, I see that for some reason you took the original "Pairs Trading" strategy from the Intermarket folder...

...and edited it to the extent that it broke, removing all calls to SetContext etc. Pair trading is typically accomplished through making a call to SetContext. Restore the script's skeleton as it originally was, execute it in Single Symbol mode, and it should work.

I actually just copied those few lines because I liked setting up the symbols as variables. The rest was written from scratch, so it just started out broken.

The write up for "Pairs Trading" says that it takes a long position in one stock and a short position in the other stock simultaneously. I just want to flip back and forth between two stocks.

Okay, then I take my words back. Please give this a try:
