Topic: Risk Percent

Hello friends,

Was wondering if anyone could help me out here.
Trying to makeing some modifications on some of my EA's, right now my objective is to try makeing my EA portifolio risk a certain % on each trade it open.

Normal from EA studio:

/*STRATEGY CODE {"properties":{"entryLots":0.03,"stopLoss":55,"takeProfit":70,"useStopLoss":true,"useTakeProfit":true,"isTrailingStop":false},"openFilters":[{"name":"Bollinger Bands","listIndexes":[2,3,0,0,0],"numValues":[28,1.74,0,0,0,0]},{"name":"Standard Deviation","listIndexes":[7,3,0,0,0],"numValues":[6,0,0,0,0,0]}],"closeFilters":[{"name":"Bollinger Bands","listIndexes":[0,3,0,0,0],"numValues":[34,3.57,0,0,0,0]}]} */
   signalList[i++] = GetExitSignal_00();
   signalList[i++] = GetEntrySignal_00();

   /*STRATEGY CODE {"properties":{"entryLots":0.03,"stopLoss":17,"takeProfit":98,"useStopLoss":true,"useTakeProfit":true,"isTrailingStop":false},"openFilters":[{"name":"Money Flow Index","listIndexes":[5,0,0,0,0],"numValues":[12,56,0,0,0,0]}],"closeFilters":[{"name":"Money Flow Index","listIndexes":[5,0,0,0,0],"numValues":[48,12,0,0,0,0]}]} */
   signalList[i++] = GetExitSignal_01();
   signalList[i++] = GetEntrySignal_01();




What im trying to achieve:

Risk Percent: Example:5%

/*STRATEGY CODE {"properties":{"entryLots":(Calculated based on the risk
5%)
,"stopLoss":5%,"takeProfit":70,"useStopLoss":true,"useTakeProfit":true,"isTrailingStop":false},"openFilters":[{"name":"Bollinger Bands","listIndexes":[2,3,0,0,0],"numValues":[28,1.74,0,0,0,0]},{"name":"Standard Deviation","listIndexes":[7,3,0,0,0],"numValues":[6,0,0,0,0,0]}],"closeFilters":[{"name":"Bollinger Bands","listIndexes":[0,3,0,0,0],"numValues":[34,3.57,0,0,0,0]}]} */
   signalList[i++] = GetExitSignal_00();
   signalList[i++] = GetEntrySignal_00();


   /*STRATEGY CODE {"properties":{"entryLots":(Calculated based on the risk
5%)
,"stopLoss":5%,"takeProfit":98,"useStopLoss":true,"useTakeProfit":true,"isTrailingStop":false},"openFilters":[{"name":"Money Flow Index","listIndexes":[5,0,0,0,0],"numValues":[12,56,0,0,0,0]}],"closeFilters":[{"name":"Money Flow Index","listIndexes":[5,0,0,0,0],"numValues":[48,12,0,0,0,0]}]} */
   signalList[i++] = GetExitSignal_01();
   signalList[i++] = GetEntrySignal_01();


Would really appreciate if anyone could help me out on this one

Thanks guys wink

Re: Risk Percent

you mean open lot size based on risk % on account balance. cause what you show is stop loss in %.

Re: Risk Percent

Yes, Roughey. That is what i meant, sorry for my explanation, abit sleepy atm smile

Re: Risk Percent

input bool                usePercent                        = true;                // Use Risk Percent base on AccountBalance
input double               Entry_Percent              = 2.00;                 // ENTRY PERCENT
Put in OnTick this:
if(usePercent==true)
      int margin=(int) MarketInfo(_Symbol,MODE_MARGINREQUIRED);
         Entry_Amount=(Entry_Percent/100)*AccountEquity()/margin;}

Re: Risk Percent

Thank you Roughey, appreciate your effort helping out members smile

But it seems like i have some issue inserting it to my EA

This i what i did:

I inserted these two lines, almost at the begining

input bool                usePercent          = true;     // Use Risk Percent base on AccountBalance
input double               Entry_Percent        = 2.00;                 // ENTRY PERCENT

I may be wrong but I believe it is because you have Entry amount as a Static Input. Trying removing the word static and compile

7 (edited by Roughey 2019-10-16 22:00:15)

Re: Risk Percent

yes delete the static and than it must work..also you have to check if entry amount is possible to your broker..so you have to normalize it.

      int margin=(int) MarketInfo(_Symbol,MODE_MARGINREQUIRED);
         Entry_Amount=(Entry_Percent/100)*AccountEquity()/margin;}
ADD THIS--->        Entry_Amount = NormalizeEntrySize(Entry_Amount);

add this


and add this outside ontick

double NormalizeEntrySize(double size) {
   double minlot  = MarketInfo(_Symbol, MODE_MINLOT);
   double maxlot  = MarketInfo(_Symbol, MODE_MAXLOT);
   double lotstep = MarketInfo(_Symbol, MODE_LOTSTEP);

   if (size <= minlot)
       return (minlot);

   int steps = (int) MathRound((size - minlot) / lotstep);
   size = minlot + steps * lotstep;

   if (size >= maxlot)
       size = maxlot;
       
   size = NormalizeDouble(size, digits);   

   return (size);
}   

Re: Risk Percent

So i did the change, but it seems like the Entry_Amount error is still the problem.

So i removed the static from the Entry_Amount

Re: Risk Percent

you are using Entry_Amount 2 times.. one time for your calculation and one time here

void OpenPosition(Signal &signal)
  {
   for(int attempt=0; attempt<TRADE_RETRY_COUNT; attempt++)
     {
      int    ticket     = 0;
      int    lastError  = 0;
      bool   modified   = false;
      int    command    = OrderDirectionToCommand(signal.Direction);
      double amount     = Entry_Amount;

So he is taking the 0,01 lots.


So you make it like this

#define OP_FLAT           -1

// Session time is set in seconds from 00:00
const int sessionSundayOpen           = 0;     // 00:00
const int sessionSundayClose          = 86400; // 24:00
const int sessionMondayThursdayOpen   = 36000; // 10:00
const int sessionMondayThursdayClose  = 61200; // 17:00
const int sessionFridayOpen           = 36000; // 10:00
const int sessionFridayClose          = 61200; // 17:00
const bool sessionIgnoreSunday        = true;
const bool sessionCloseAtSessionClose = false;
const bool sessionCloseAtFridayClose  = false;


input bool useFixLot = false; //Use Fix Lot
input double FixLot = 0.01; // Fix Lotsize
input bool                usePercent                        = true;                // Use Risk Percent base on AccountBalance
input double             Entry_Percent              = 2.00;                 // ENTRY PERCENT



const int    strategiesCount = 10;
const double sigma           = 0.000001;

datetime barTime;
int      digits;
double   stopLevel;
double   pip;
bool     setProtectionSeparately = false;
double Entry_Amount;

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+

AND IN ONTICK ADD THIS

if(usePercent==true)
      {
      int margin=(int) MarketInfo(_Symbol,MODE_MARGINREQUIRED);
         Entry_Amount =(Entry_Percent/100)*AccountEquity()/margin;
         Entry_Amount = NormalizeEntrySize(Entry_Amount);
Comment("Next Lotsize: "+DoubleToString(Entry_Amount));    <---Optional
      }
if(useFixLot == true)
{
Entry_Amount = FixLot;
}

This must working!!!

Re: Risk Percent

Roughey! It finally works!

Did several tests, and it seems like it works perfectly. Will be putting out some EA's next week and see how it goes.

Thank you again for helping me out, really appreciate it Roughey.

Re: Risk Percent

One more thing, if it's not to much to ask.

Is it possible to make the EA only have 1 trade open at once?

So if there is an open position no new trade will be executed before the old position is closed

Thanks.

Re: Risk Percent

Hello Roughey,

So i have been trying out the code for one week now, and it works, but there is still something missing.

When i put 10 in the Entry Percent input, the EA dont risk 10% of the account balance/equity but risk only 2-3%.


Why and do i miss something?


Thanks and happy weekend guys!
