Help: Need code to increase lot size per $1000 increase in account

I need a code to increase my initial lot size per $1000 increase in account balance in the pattern below

Balance__________________Lot Size
1000 1000/1000 0.1 (Initial lot size)
1500 1500/1000 0.1
2000 2000/1000 0.2
2900 2900/1000 0.2
3100 3100/1000 0.3
3600 3600/1000 0.3

Can someone help show me how to code it for a mini account ?
double Thousands = AccountBalance() / 1000;
double RoundDown = MathFloor(Thousands);
double Lots = RoundDown / 10;

So if you had $2939.66 in the account, the first statement would give you 2.93966;
The next line would give you 2;
last line would give 0.2.

try it out on demo and if it doesn't work, move a decimal point.

I have implementing the suggestion into the EA attached but, I could not get it to work correctly when balance past the $2000 mark, can anyone help ?

Inserted Code
extern bool      MoneyManagement=true; 
...
...

int start()
 {
 
//+------------------------------------------------------------------+
//| MoneyManagement to increase "lots" & "buylots" size base on per $1K increase in balance                                          |
//+------------------------------------------------------------------+
if (MoneyManagement)    
   {
     double Thousands = AccountBalance() / 1000;
      double RoundDown = MathFloor(Thousands);
            if (RoundDown < 1) { RoundDown =1; }
//+------------------------------------------------------------------+
//Due to my limited coding skill, the problem seem to lie here as when account > $2000, code does not work properly|                                         |
//+------------------------------------------------------------------+ 
            
      lots= lots * RoundDown;
      buylots = buylots * RoundDown ;
//+------------------------------------------------------------------+
// May not be necessary if the coding of lot size is done properly                                        |
//+------------------------------------------------------------------+     
      if(lots < 0.2) { lots =0.2; }
      if(buylots < 0.19) { buylots =0.19; }
    }
    
  if(MoneyManagement==false)
   {
     lots=lots;
     buylots=buylots;
   }   
.......

I'm no expert, but, I think because you have a couple or return(0) in there before it gets to order send so it just keeps multiplying the lots.

I left my working out so you can follow the working out of an amateur. I use the Print function a lot in fault finding.

cheers
