Stock Standard Percentage Position Sizing

Hi All,

I'm a newbie to this forum.
There looks to be lots of great topics and contributors.
I've been studying for the past 5 years and trading the last 2.
I trade forex and have only recently changed from MT4 to Tradestation.

I've been searching for the last few weeks over the Christmas Holliday Season,
For a "Flat Rate Percentage Position Sizing Code" for EasyLanguage.
To add to my strategy code.

I just can't find one!
There are heaps of volatility and risk based position sizing codes.
And I have tried to modify them, but they will not verify.

I was looking for some help form you all in finding or modifying some code.

All that I want to do is:

Use a flat rate of 2% of Account Equity to enter and exit trades.

My strategy is a low to medium time frame (depending on the Pair)trending strategy and I am constantly in the market.

I am by no means a programmer.
I've read miles of code, watched gigabytes of videos on codes being applied to strategies and have copied and pasted
codes to implement my strategy code.
I have now been trading it on Mt4 manually for the last 3 years (13 months Demo and 2 Years on a Live Account) and have been testing it on Tradestation forex and stocks on demo for 13 months, and I'm ready for it to take over my manual trading.
( too many late nights trading the London/Neywork cross over as I live in Australia)

Entries and Exits are coded as Follows:

Long:
If Trend_S > Trend_S[1] then
Buy this bar at close;

Short:
If Trend_S < Trend_S[1] then
SellShort this bar at close;

I Hope that one or a group of you guys can help me and maybe others looking for this on the web.

Hope to Hear From You's Soon.

"May the pips be forth coming,
the drawdowns low and infrequent,
In your trading for 2013."
