Stop loss percentage formula - Help

Hi,I  want to have a stoploss  for my back trades if the price increases  20% take loss.
An example i place a back trade at 4.6 the price increases 20% to 5.8 12 ticks i want to exit trade, i would i do ?

Sorry how would i do the above?

Hi
Just use the distribute loss trigger action. You can choose either based on ticks or based on %.

You can also use the stop loss options in the settings.

and here are some example stop loss triggers.  

The simplest option is to do "distribute the loss" at 20% loss (use the corresponding trigger settings).

Thanks both am I correct in saying the attached will trigger  stoploss if my back bet goes 6% in the red?

Hi
I tested it in Time Machine and it does just that.
I changed the back amount to £10, and if the trade went into the red by 6% it distributed £0.61 loss evenly across all selections. 

Great thanks Mark. How can i get this trigger to repeat,  i created  a trigger request however its saying my quote is exceeded tho i cancelled other requests,  could you help please?

sorted it now thanks
