Money management help with step size of lot increasing

Hi, I’m new to this and I’m having trouble to make this money management code for my system to work the way I want it to. I found a nice code with fixed fraction that member Despair hade posted some time ago: once multiplier=1 once fraction=1000 once newlevel=1000 once oldlevel=1000 once startpositionsize=1 once positionsize=startpositionsize if strategyprofit>newlevel then multiplier=multiplier+1 oldlevel=newlevel newlevel=strategyprofit+multiplier*fraction positionsize=multiplier*startpositionsize elsif strategyprofit =2 then newlevel=strategyprofit oldlevel=strategyprofit-multiplier*fraction multiplier=multiplier-1 positionsize=multiplier*startpositionsize endif The code works exactly the way i want it to, however I want the system to start at 3 contracts instead of 1. But when I try to raise my startPositionSize to 3.. every time I make profits/losses it increases/decreases the next positionsize by 3 instead of 1. e.g. 3, 6, 9, 12, 9 , 12, 15 etc. I want it to start with 3 contracts and then increase/decrease positionsize by only 1 contract steps at the time based on profits/losses. e.g. 3, 4, 5, 6, 5, 4, If someone can help me with this I would be very grateful!

Hi,

I’m new to this and I’m having trouble to make this money management code for my system to work the way I want it to.

I found a nice code with fixed fraction that member Despair hade posted some time ago:
```
once multiplier=1
once fraction=1000
once newlevel=1000
once oldlevel=1000
once startpositionsize=1
once positionsize=startpositionsize
if strategyprofit>newlevel then
  multiplier=multiplier+1
  oldlevel=newlevel
  newlevel=strategyprofit+multiplier*fraction
  positionsize=multiplier*startpositionsize
elsif strategyprofit<oldlevel and multiplier>=2 then
  newlevel=strategyprofit
  oldlevel=strategyprofit-multiplier*fraction
  multiplier=multiplier-1
  positionsize=multiplier*startpositionsize
endif
```
The code works exactly the way i want it to, however I want the system to start at 3 contracts instead of 1. But when I try to raise my startPositionSize to 3.. every time I make profits/losses it increases/decreases the next positionsize by 3 instead of 1.

e.g. 3, 6, 9, 12, 9 , 12, 15 etc.

I want it to start with 3 contracts and then increase/decrease positionsize by only 1 contract steps at the time based on profits/losses.

e.g. 3, 4, 5, 6, 5, 4,

If someone can help me with this I would be very grateful!

We need to create a new variable named “step” at the beginning of the code:
```
once multiplier=1
once fraction=1000
once newlevel=1000
once oldlevel=1000
once startpositionsize=1
once positionsize=startpositionsize
once step = 1

if strategyprofit>newlevel then
  multiplier=multiplier+1
  oldlevel=newlevel
  newlevel=strategyprofit+multiplier*fraction
  positionsize=multiplier*step//startpositionsize
elsif strategyprofit<oldlevel and multiplier>=2 then
  newlevel=strategyprofit
  oldlevel=strategyprofit-multiplier*fraction
  multiplier=multiplier-1
  positionsize=multiplier*step//startpositionsize
endif
```
That should work, I have not tested it, please do 😉

Thx alot Nicolas! 😀

Works better!

However, the first time when it’s suppose to increase the contractssize from 3 to 4, it starts over from 2 contracts and then works it’s way up from that point one step at the time.

E.g. I start my backtest with 3 contracts as the startingpoint, everything works fine. But then when I have reached my first strategyprofit step (profit), it goes down to 2 contracts, when I actually would like it to go up to 4 contracts.

Do you know how to solve this last piece of the puzzle? 🙂

Hmm.. if you only want to increase/decrease your lot size according of when you loose or win, that code is not really appropriate!
