Incorrect stock prices

Daniel Merkel, the manager of The Spirit of Nicolas Darvas broadcasted this message:

“Two weeks ago, I bought the stock EDN for the system (and also for myself personally). With the buy order, I placed a stop loss of $5.11. Unfortunately, in Collective 2’s imagination, this position was stopped out, even though the lowest price the stock ever traded at was $5.33.”

"The executions I have been getting have been so inaccurate, that I will not be using stop orders for new positions."

I asked him what was C2 response to these problems and he replied:

"The last two times I contacted C2, my emails went unanswered."
