Fix ninjatrader script

I am routinely getting these 2 errors from my automated system. Sometimes the system will fail to close a trade once one is opened, other times no trades will be taken, other times it will execute properly but then disable itself. I am looking for a way to fix these errors so my system works without shutting itself off repeatedly
