I wrote this indicator that will display current initial margin requirements to open positions with no stop, a non guaranteed stop and a guaranteed stop:

DEFPARAM calculateonlastbars = 1

Size = 1 //Your Trade Size
MarginFactor = 5 //Margin Factor in %
SlippageFactor = 50 //Slippage Factor in %
StopDistance = 100 //Stop Distance in pips
LimitedRiskPremium = 1 //Limited Risk Premium

NoStopMargin =(Size * close) * (MarginFactor / 100)
NoStopMargin = Round(NoStopMargin * 100) / 100

StopMargin = (Min((NoStopMargin * (Slippagefactor / 100)) + (Size * StopDistance),NoStopMargin))
StopMargin = Round(StopMargin * 100) / 100

GStopMargin = (Size * StopDistance) + (Size * LimitedRiskPremium)
GStopMargin = Round(GStopMargin * 100) / 100

DRAWTEXT("No Stop Margin #nostopmargin#",barindex,0,SansSerif,Bold,16)coloured(0,0,255)
DRAWTEXT("Stop Margin #stopmargin#",barindex,-0.5,SansSerif,Bold,16)coloured(0,0,255)
DRAWTEXT("Guaranteed Stop Margin #gstopmargin#",barindex,-1,SansSerif,Bold,16)coloured(0,0,255)

return 0.5,-1.5

The calculations are taken from IG’s information on the charts on their platform.

You will need to put in the correct values for each of the factors involved in the calculation for whichever instrument you apply it to.

I have not found any information yet saying what the values for the Limited Risk Premium used in the guaranteed stops calculation are and IG do not list it in the chart information.

ITF file also attached.

I wrote this snippet that can be added to long only strategies with no stops to graph the maximum margin required in a back test. It could be adapted to short and with stops using the calculations in the indicators but I will let someone else do that as I would never use it!

MarginFactor = 5 //Margin Factor in %

NoStopMargin = (CountOfPosition * low) * (MarginFactor / 100)
InitialMargin = Round(NoStopMargin * 100) / 100

MaintenanceMargin =   (CountOfPosition * PositionPrice) - (CountOfPosition * low)

TotalMargin = 0 - (InitialMargin + MaintenanceMargin)

if not onmarket or TotalMargin > 0 then
TotalMargin = 0
endif

I think it works correctly but if any one spots a bug or error in it or any of the other codes here then please correct them as none of them have really been tested properly.
