I’ve never used spreadbetting but I dont think there’s any difference for autotrading. Others may be able to confirm this.

It runs on the DJI for which there are different position size and currency options: $10 $2 or €1. The results I have posted are for 1 contract = €1

If you’re trading in $ then the min / max positionsize will be different

If you have a UK IG account, the MM should look like this:

//Money Management DJ
MM = 1 // = 0 for optimization
if MM = 0 then
positionsize=.4
ENDIF
if MM = 1 then
ONCE startpositionsize = .4
ONCE factor = f // factor of 10 means margin will increase/decrease @ 10% of strategy profit; factor 20 = 5% etc
ONCE margin = (close*.05) // tier 1 margin value of 1 contract in instrument currency; change decimal according to available leverage
ONCE margin2 = (close*.05)// tier 2 margin value of 1 contract in instrument currency; change decimal according to available leverage
ONCE tier1 = 55 // IG first tier margin limit
ONCE maxpositionsize = 550 //  IG tier 2 margin limit
ONCE minpositionsize = .2 // enter minimum position allowed
IF StrategyProfit <> StrategyProfit[1] THEN
positionsize = startpositionsize + Strategyprofit/(factor*margin)
ENDIF
IF StrategyProfit <> StrategyProfit[1] THEN
IF startpositionsize + Strategyprofit/(factor*margin) > tier1 then
positionsize = (((startpositionsize + (Strategyprofit/(factor*margin))-tier1)*(factor*margin))/(factor*margin2)) + tier1 //incorporating tier 2 margin
ENDIF
IF StrategyProfit <> StrategyProfit[1] THEN
if startpositionsize + Strategyprofit/(factor*margin) < minpositionsize THEN
positionsize = minpositionsize //keeps positionsize from going below allowed minimum
ENDIF
IF (((startpositionsize + (Strategyprofit/(factor*margin))-tier1)*(factor*margin))/(factor*margin2)) + tier1 > maxpositionsize then
positionsize = maxpositionsize// keeps positionsize from going above IG tier 2 margin limit
ENDIF
ENDIF
ENDIF
ENDIF

The tiers are actually redundant in this case as the tier 1 and tier 2 margin requirements are the same (in some countries they differ).

I have used .4 as a default starting position as it is roughly equivalent to €1 on the DAX or NAS, but you can put anything you like for startpositionsize =

Factor is what controls how quickly/slowly the positionsize increases/decreases with strategyprofit.

f = 10 means that if you have a €100 win/loss, the margin of the next trade will increase/decrease by €10

f = 20 means the margin of the next trade would increase/decrease by €5

I would not recommend going below f = 8

Hope this helps!

.4 is 40 euro cents. £2 per point would be around €2.2

because of the size of the DOW (30k) you are just using a smaller starting size for margin requirements?

yes, exactly.
