I am going through the programming course done by codeguru, and it references this site as the location to download the samples in the tutorial, but I cannot find them anywhere. Can anyone help me?

Thanks!

i am quite nude in this field. i'm trying to program the following EA with great difficulty: can anyone help direct me.

on H1 timeframe, if MA13 (moving average set to 13) goes above (crosses) MA120
and
stochastic 120 > 50 and
sto 15 > 60

then buy

if MA 13 goes below MA120 and
sto 120 >50
and sto 15 <20
then sell

with the parameters changeable

HI Coders Guru,

I'm not at this stage interested in developing EAs, scripts, indicators etc, I just need to know what the various options/settings are on MT4 e.g. how to change bear & bull colours on candle charts globally not just for individual charts. Will your tutorial tell me things like that, or will it over the top for a FOREX newbie like myself?

Cheers,

Mike

Here is what i use on my ea

Quote:

extern bool UseMM = True;
extern bool Micro = True;
extern double Lots = 0.01;
extern double Risk = 0.1;
extern double MinLots = 0.01;
extern double MaxLots = 100.0;

//+------------------------------------------------------------------+
//| calculate optimal lot size |
//+------------------------------------------------------------------+

double LotsOptimized()
{
//----
double lot = Lots;
int orders = HistoryTotal(); // history orders total
int losses = 0; // number of losses orders without a break

if(UseMM){
if(!Micro){
lot = NormalizeDouble((Risk*AccountFreeMargin())/1000,1);
if(lot>MaxLots){lot=MaxLots;}
else if(lot<MinLots){lot=MinLots;}
}
else{
lot = NormalizeDouble((Risk*AccountFreeMargin())/1000,2);
if(lot>MaxLots){lot=MaxLots;}
else if(lot<MinLots){lot=MinLots;}
}
return(lot);
}
else{
return(Lots);
}
}

here is some of others best of MM

Quote:

extern double Lots = 0.01;
extern double DecreaseFactor = 0.3;
extern int Leverage = 200;

double LotsOptimized()
{
double lot=Lots;
int orders=HistoryTotal(); // history orders total
int losses=0; // number of losses orders without a break
//---- select lot size
lot=NormalizeDouble(Risk*AccountFreeMargin()* AccountLeverage()/100000.0,1);
//---- calcuulate number of losses orders without a break
if(DecreaseFactor>0)
{
for(int i=orders-1;i>=0;i--)
{
if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)==fals e)
{ Print("Error in history!"); break; }
if(OrderSymbol()!=Symbol() || OrderType()>OP_SELL) continue;
//----
if(OrderProfit()>0) break;
if(OrderProfit()<0) losses++;
}
if(losses>1) lot=NormalizeDouble(lot+lot*losses*DecreaseFactor, 1);
}
//---- return lot size
if(lot<0.01) lot=0.01;
return(lot);
}

Can someone suggest to me how to combine both coding into one ...?
your help, hope me win on my eas...

1st order open sell/buy loss,
then
2nd open order sell/buy increase double (2x) from previous lots...to cover loss from 1st order... hope it may win...

main things is i want to recover every losses i made by increasing the lot after each losses...

thank you...

regards,

I'm an old guy but I like to learn something that is maybe useful to me and/or my kids.

Anyway, is there any update and/or development and/or suggestion since you release EMA_CROSS_2.mq4 which is quiet good for me but I saw that still we can further develop it so it can reduce the MODIFY function into more positive order closing one.

Again, thanks a lot,
John

hi

i have wrote an ema cross over as well but have some problems with it
i have wonder if you can look at it or can i look at your system. we can work together to improve it

Hello all,

Would a coding expert kindly explain:

when code should be written within the function init() ?
when code should be written within the function deinit() ?

I have been looking for the answer to these questions on the internet but I got nothing that explains it in clear practical application terms.

examples would help...

Thanks in advance.
