How would you code a money management feature into an EA...

for example:

If balance is $500 or less trade 0.1 lots
If balance is $1000 or more trade 0.2 lots
If balance is $1500 or more trade 0.3 lots
If balance is $2000 or more trade 0.4 lots
If balance is $2500 or more trade 0.5 lots
If balance is $3000 or more trade 0.6 lots
If balance is $3500 or more trade 0.7 lots
If balance is $4000 or more trade 0.8 lots
If balance is $4500 or more trade 0.9 lots
If balance is $5000 or more trade 1.0 lots
If balance is $5500 or more trade 1.1 lots
etc for every $500 increment in balance add 0.1 lot

If you attach your EA someone will most likely code it.

Best regards

Just divide your balance by 5000 and save it as lotsize.

i use only ibfx, but after sharing ea's and every1 using diferent brokers
i needed a money management that worked on all brokers without changing anything

this works on 4 & 5 digits

heres my money management
iv tested on 3 diferent brokers, including variouse leverages
odl, ibfx, sparren.

this is a simple script to open a buy position
wrather your using the sl feature or not, the sl is the pips, the risk is the %
of account per pips

Inserted Code

#property show_inputs

double risk=3.5;
extern int stop_loss=25;


bool use_sl=false;
double my_point,digits,sl;


int start()
{
  if (Point==0.0001)my_point=0.0001;
  if (Point==0.00001)my_point=0.0001;
  
  if (Point==0.01)my_point=0.01;
  if (Point==0.001)my_point=0.01;
  
  if (use_sl)sl=Ask-stop_loss*my_point;
  if (!use_sl)sl=NULL;
  
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.001)digits=3;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.01)digits=2;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.1)digits=1;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==1)digits=0;

double lots=(AccountFreeMargin()/MarketInfo(Symbol(),MODE_MARGINREQUIRED)/AccountLeverage())*risk/(100*my_point)/stop_loss;

if (lots<MarketInfo(Symbol(),MODE_MINLOT)) {lots=MarketInfo(Symbol(),MODE_MINLOT);}
if (lots>MarketInfo(Symbol(),MODE_MAXLOT)) {lots=MarketInfo(Symbol(),MODE_MAXLOT);}

lots= NormalizeDouble(lots,digits);

OrderSend(Symbol(),OP_BUY,lots,Ask,3,sl,NULL,"script",NULL,0,CLR_NONE);



return;
}

this is the line with the math

Inserted Code

double lots=(AccountFreeMargin()/MarketInfo(Symbol(),MODE_MARGINREQUIRED)/AccountLeverage())*risk/(100*my_point)/stop_loss;

heres the breakdown of the math
free margin divided by the amount required to open 1 lot divided by leverage

this returns 1% of the account in 100 pips

i added this, to edit the risk and pips
*risk/(100*my_point)/stop_loss;

TJ,

That would be too simple.

What I am looking to do is to incrementally increase lot size based on current balance before each trade. As equity increases, by a set amount, in this case $500 each trade is incrementally 0.1 lot size higher. If/When the balance exceeds $5000 then it would trade in 1.0 to 1.1 increments and so on. At 10k it would trade at 2.0 lots at 10,500 in equity it would trade 2.5 lots, etc.

This code would need to be processed in real time so when trades were fired off while I was sleeping the maximum number of lots or mini lots would be traded based on required equity per increment.

Trendchaser, thanks for sharing.

I use ibfx and was wondering how would that be implemented in a sample ea like the one attached below which was created by "Metatrader" and posted on another thread a few days ago.

I would like to be able to define the amount needed for each 0.1 lot size in dollars. For now it's $500 per 0.1 or mini lot per trade. So for example a free margin of $2450 would fire off a buy or sell with a 0.4 lot size and $2650 would fire off a 0.5 lot size trade. The free margin would be calculated in real time before each trade.

The main purpose of course is to allow this money management feature to trade the maximum amount that I allocate even while trades are fired off while I sleep

put this at the top of the code

Inserted Code

extern double risk=3.5;
extern int stop_loss=25;


bool use_sl=false;
double my_point,digits,sl;

put this after start()

Inserted Code

if (Point==0.0001)my_point=0.0001;
  if (Point==0.00001)my_point=0.0001;
  
  if (Point==0.01)my_point=0.01;
  if (Point==0.001)my_point=0.01;
  
  if (use_sl)sl=Ask-stop_loss*my_point;
  if (!use_sl)sl=NULL;
  
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.001)digits=3;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.01)digits=2;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==0.1)digits=1;
if (MarketInfo( Symbol(), MODE_LOTSTEP)==1)digits=0;

double lots=(AccountFreeMargin()/MarketInfo(Symbol(),MODE_MARGINREQUIRED)/AccountLeverage())*risk/(100*my_point)/stop_loss;

if (lots<MarketInfo(Symbol(),MODE_MINLOT)) {lots=MarketInfo(Symbol(),MODE_MINLOT);}
if (lots>MarketInfo(Symbol(),MODE_MAXLOT)) {lots=MarketInfo(Symbol(),MODE_MAXLOT);}

lots= NormalizeDouble(lots,digits);

now, in all of the ordersend functions, put lots and sl
(sl is optional)

Inserted Code

OrderSend(Symbol(),OP_BUY,[b]lots[/b],Ask,3,[b]sl[/b],NULL,"script",NULL,0,CLR_NONE);

anywhere you used Point
replace it with my_point

thats it, if you leave bool use_sl=false;
theres no sl

if you change it to bool use_sl=true;
youl have a sl

play with the risk setting until you achieve the desired lots increment

AccountFreeMargin() can be replaced with accountequity or accountbalance
though it wouldnt make much diference

This is how I would have done it. I wrote a little function, that is the logic and then I put it in a indicator that calls it so you can see how it is used.

PHP Code

// Function to return a incremnted lot amount for a given balance by dollar increments.
double      Lotsize(double acctbalance, double increment, double baselot)
   {                     //AccountBalance     every$500         0.01 for every $500
     
      int lotmultiple = acctbalance/increment;
      double lots = baselot*lotmultiple;
      return(lots);
   }

      double lots = baselot*lotmultiple;
      return(lots);
   }

Thank you Sir.
