Yahoo - Stops & Targets in EFS strategies

[dloomis]

I was trying to wright a strategy that would go long when price
closes above MA +1 and short when close -1. I also wanted to set a 5
point/dollar stop if the price goes against the position and the 25
point/dollar target. I made the EFS using Formula Wizard but couldnt
implement stop and the target. I would appreciate any help on this
matter.
Thank you.

I had to insert close()+5 for the stop by hand, but this is what I would have done.

Thank you David for your reply.
I have fine tuned the EFS a little to be more like i wanted.
Now when i back test it if the strategy goes short at bars close and the same bars high was more or equal to +5 then the strategy exits at the same bar.
Example from back testing:
Short 02/05/2003 14.00 $849.00 1 ($-5.00) $4.25 0.00%
Cover Stop Order 02/05/2003 14.00 $854.00 1 ($-85.50) ($-6.25)

Here is the formula , maybe i made a mistake somewhere if you can point it out to me.
Thank you.

I think you need to read

http://share.esignal.com/download.js...er=&file=Guide To Developing eSignal Strategies.doc

and check out the Market orders this bar parts, maybe some one else will explain how to enter mid bar, but I think there are some examples in the doc I refer to above

[dloomis]

that link got messed up in the cut and paste, you need to type all of the text into the address area, fyi

[dloomis]

http://share.esignal.com/groupcontents.jsp?folder=&groupid=33

is where tha doc lives

and you need

setColorPriceBars(true);

in preMain() to get the colors to show on the bars.

Thank you , was looking for some kinda guide to EFS for a while now. Your link didnt work so i did a serch at eSignal share and found two docs in eSignal Group - Docs section. This probably is the one.
