Cross and Exit rules

[David Beaudoin <dcbeaudoin@xxxx>]

Dear Tomasz,

I am rather reluctant to ask for help because I know how busy you are 
trying to complete version 3.6, but I am becoming increasingly frustrated 
with my inability to figure out how to progress further in what I am doing.

First of all, I am confused about the "cross" function. If I want to take 
a long position only if (among other things) today's price trades 0.05 
above yesterday's high, I would think that the following would capture that:

buyprice = ref( high,-1 ) + 0.05;
buy = cross ( high, buyprice);

However, this does not always trigger an appropriate signal, as compared to:

buyprice = ref( high,-1 ) + 0.05;
buy = (high >= buyprice );

What is the difference?

Secondly, I am really struggling with rules to Exit (both sell and cover) 
positions. I am essentially looking to have positions closed in either a 
6-point profit or a 4-point loss. Yet, when I enable the Stops in the 
"Settings" menu, my reports show me exiting positions without either of 
those conditions being met. I understand that in some of these cases, the 
system is closing and reversing because the entry conditions have been met 
for the opposite direction, but there are many more instances where that 
isn't the case and the trade is exited arbitrarily. I have even tried to 
disable the Stops and just do the following, but I still get the same outcome:

sell =(( high >= (buyprice + 6)) OR ( low <= (buyprice - 4)));
cover =(( low <= (shortprice - 6)) OR ( high >= (shortprice + 4)));

Is there any chance you could help me out? I was enjoying the program 
tremendously, but I have really become discouraged by my lack of progress 
in overcoming these questions.

Sincerely,

David Beaudoin
