Issue with Fixed Risk Hotkey in DAS — Not Buying Correct Share Size

[Alex Dumitrache 0]

Hey everyone, I need some help with a fixed risk hotkey I’m using in DAS.

My goal is:

• Risk a fixed dollar amount (e.g., $100).

• Buy (or short) the maximum number of shares based on:

  • My stop loss (selected by double‑clicking on the chart).

  • My available buying power.

Here’s the hotkey I’m currently using for long entries:

StopPrice=Price-0;
DefShare=BP*0.925;
Price=Ask-Price+0.00;
SShare=98/Price;
Share=DefShare-SShare;
DefShare=DefShare+SShare;
SShare=Share;
SShare=DefShare-SShare;
Share=0.5*SShare;
TogSShare;
ROUTE=SMRTL;
Price=Ask+0.05;
TIF=DAY+;
BUY=Send;
DefShare=200;
TriggerOrder=RT:STOP STOPTYPE:MARKET PX:StopPrice-0.05 ACT:SELL STOPPRICE:StopPrice QTY:Pos TIF:DAY+

and for Short:

StopPrice=Price+0; 
DefShare=BP*0.925; 
Price=Price-Bid+0.00; 
SShare=98/Price; 
Share=DefShare-SShare; 
DefShare=DefShare+SShare; 
SShare=Share; 
SShare=DefShare-SShare; 
Share=0.5*SShare; 
TogSShare; 
ROUTE=SMRTL; 
Price=Bid-0.05; 
TIF=DAY+; 
SELL=Send; 
DefShare=200; 
TriggerOrder=RT:STOP STOPTYPE:MARKET PX:StopPrice+0.05 ACT:BUY STOPPRICE:StopPrice QTY:Pos TIF:DAY+
 

The Problem

When my stop is very tight (usually less than $1 away from entry), DAS calculates the wrong share size.

Current Example (short trade):

• Buying Power: $40,000

• Entry: $320.33

• Stop: $321.13 (double‑clicked)

• Risk: $0.80 per share

• Risk I want: $100

• Shares DAS actually bought: 71

Math check:

• 71 shares × $320.33 = $22,743 (almost half of my BP)

• 71 shares × $0.80 = $56.8 risk

• Should have been closer to 100 shares (to risk ~$100)

So instead of hitting my defined risk, DAS under‑allocates shares when the stop is tight.

What I Need Help With

I’m looking for a clean hotkey script that:

• Risks a fixed dollar amount (e.g., $100).

• Correctly sizes the position based on the distance to my stop (no matter how tight).

• Respects available buying power.

Has anyone solved this issue or can help me rewrite the script correctly?

Thanks in advance!

Share=0.5*SShare; 

the 0.5 means half. if you want whole size remove the 0.5* from the equation.

you have several steps that guarantee you will not risk $100 neither use 100% of the BP
