Shaun,
Let's see if I can totally confuse you. :-)
Straight from Metastock help[top line of your program]:
IF FUNCTION:A conditional function that returns the second parameter
(THEN) if the conditional expression defined by the first parameter
is true; otherwise, the third parameter is returned (ELSE).
EXAMPLE The formula "if(1<2,3,4)" will always return the value three.
Another way to look at this is:
if(condition,value,null)
or if the condition is true,{then} use this value,{else} no value.
In your case it would be:
if({share bought},{stop loss},0)
In your case you will need to consider several factors:
1.Will the actual date of the purchase be needed or could you simply
use a trigger or barsince condition?
2.In this example you would plot either the stop loss or zero.The
value between the stop loss and zero may be large. If plotted on a
price chart it would require a plot of 0 to the stop loss value and
if prices are around 100 or greater you would have a large price
display. If plotted in a seperate window it may not be as
significant. Consider also that this is the case if you plot from
left to right or from the beginning of the price display. Another
option and I think what you may be looking for is to plot from right
to left or from today backwards. This is unorthodox to metastock BUT
I have seen it done. Let me look through some older post and see if I
can scrounge up the solution. In the mean time maybe some others will
be able to glean another method to accomplish the task.
