How to code? - Page 215

Hello

I have been attempting to make a SL that it derived from the % risked and Lot Size.

Example

Balance 2000
Risk 2%
Cash At risk $40.00 = Balance * Risk
Lot Size 0.02
TickValue 10.00 or as determined by each pair.
TickSize 0.2 = TickValue * LotSize

SL 200 = Cash at Risk / TickSize.

So the SL would be placed 200 pips from the open.

the Lot Size should increase by 0.01 every 1000 Dollars.

This is what I have so far

Code:

double Lots;
if(OrderSelect(0,SELECT_BY_POS,MODE_HISTORY)) {
  if(OrderType()==0 && OrderProfit()>0) {
  if(AccountBalance()>1000*2) Lots=MathAbs(MathCeil(-AccountBalance()/OrderProfit()))*0.01;
else Lots=0.01;

Any Help would be great

Cheers

Beno

Gidday

How do you use the bar open as the pivot point. example

If the Bid moves above the open buy and hits TP (with any luck) and reverses then the Ask moves below the open so open a sell.
I do realize the if the TP is not hit and the could be another position opened.

any help would be great.

Regards

Beno

Hi,
I want to write my own EA.
First I send a SellLimit and a BuyLimit.

Then I want to see, which Orders of them are reached. How can I see which order is still open??

When I look at OrdersTotal() is get my OPEN and PENDING Orders.

Lot's of thanks,

sunshineh

by OrderType( )

OP_BUY - buying position,
OP_SELL - selling position,
OP_BUYLIMIT - buy limit pending position,
OP_BUYSTOP - buy stop pending position,
OP_SELLLIMIT - sell limit pending position,
OP_SELLSTOP - sell stop pending position.

PHP Code:


			
for (int i = 0; i < OrdersTotal(); i++) 

   {

      OrderSelect(i, SELECT_BY_POS, MODE_TRADES);

      if(OrderType() == OP_BUY) {...do some thing....}

      if(OrderType() == OP_SELL) {...do other thing....}

   }

Hi Everyone,

This is my first post!!

I have been trying for about 3 months to program an EA to recognise a particular candlestick pattern and open either a Buy or Sell order after that pattern but, have been failing miserably!

I don't know how to post pictures here so I'll have to describe it.

For a Buy signal / trade I have been trying program:

Close[3] < Close[4],
Close[2] < Close[3],
High[2] < Open[3],
Low[1] > Low[2] and
Close[1] >= Open[3]

For the Sell signal / trade it is the opposite of the Buy.

It is probably very simple but I just can't do it.

Is there a kind and generous person out there who would be willing to program this for me???

Thanks

Hi Cgage....

Without your code I don't know what your variables are but you can try and modify this...it may work for you.

bool BuyCondition = false ;
bool SellCondition = false ;

//--------- BuyCondition ----------
if (Close[3] < Close[4] && Close[2] < Close[3] && High[2] < Open[3] && Low[1] > Low[2] && Close[1] >= Open[3]) BuyCondition = true ; else BuyCondition = false;

For the Sell signal / trade it is the opposite of the Buy.

//--------- SellCondition ----------
if (Close[3] > Close[4] && Close[2] > Close[3] && High[2] > Open[3] && Low[1]< Low[2] && Close[1] <= Open[3]) SellCondition = true ; else SellCondition = false;

Good luck.
Robert

Thanks for the reply.

I tried something like this, I've tried lots of things.

The problems I've had have been multiple trades per bar, trades on every bar, not recognising the pattern at all, etc.

I understand the logic side of things but I don't know how to program it.

I tried doing cut and paste from other indicators / EAs but I can't get it to do what I want!

Basically, if the buy condition logic = true then open a buy trade and if sell condition logic = true then open a sell trade.

Any help appreciated.

   }

This above is your solution. You need to count existing orders so EA knwos they exist and not continue creating more

See what I said above. Can also try similar to this:

PHP Code:


			
int i, ticket;



int total = OrdersTotal();



double totallongs=0, totalshorts =0; 



          

 for( i=0;i<total;i++)       

   {

     OrderSelect(i, SELECT_BY_POS );

      if ( OrderComment() == ExpertName )  

         {

           int type = OrderType();



if (( OrderSymbol() == Symbol() && (type == OP_BUY ))) {totallongs=totallongs+1;}

if (( OrderSymbol() == Symbol() && (type == OP_SELL ))) {totalshorts=totalshorts+1;}

if (( OrderSymbol() == Symbol() && (type == OP_BUYLIMIT || OP_BUYSTOP ))) {totallongs=totallongs+1;}

if (( OrderSymbol() == Symbol() && (type == OP_SELLLIMIT || OP_SELLSTOP ))) {totalshorts=totalshorts+1;}



                }

              }

Thanks Guys,

Much better, it's not trading every bar now.

I have managed to get close to what I wanted but at the moment it's not finding the pattern I was after.

Just a few logic tweaks I think.

Does anybody have or can code the percent of resistance indicator?
