Thanks Tomasz. I'm still relatively new to Amibroker, short of combing
through tons of backposts is there a good post/article somewhere on
the rational for this? Or better yet a "common AFL mistakes" post?

point out that your strategy is unrealistic! You are making a rule
where if at the END of a bar we are below an MA we should sell at a
price ABOVE the close (ie the MA price that price action is now
below). Furthermore the MA will not settle to its final value until
the bar is finished (since the MA is calculated on closing prices).
You should probably set your sell prices to the open of the next bar
