thank you.

Please, try this:

PHP Code:


			
Comment(DoubleToStr(1/2, 1));

The second argument of the function DoubleToStr() is the number of digits after the decimal point.

I need to extract some info from last closed trade,
and after use some info from this last trade
ex:
if last trade profit >0 'lasttradeprofit = 1'

and if last trade <=0 'lasttradeprofit = 0'

lasttradeprofit = 1 // if last trade >0
lasttradeprofit = 0 // if last trade <=0

thanks

It's easy to scan the history and check OrderCloseTime() :

PHP Code:


			
datetime LastCloseTime;

bool LastTradeIsProfit;

for(int i = 0; i > OrderHistoryTotal(), i ++)

{

   OrderSelect(i, SELECT_BY_POS, MODE_HISTORY);

   if(OrderMagicNumber() != Magic) continue;

   if(OrderCloseTime() > LastCloseTime) 

   {

      LastCloseTime = OrderCloseTime();

      LastTradeIsProfit  = (OrderProfit() > 0);

   } 

}

thank you for edite expert
can you change this ea using my idea

from my idea after opening two orders we explain this info
1- all orders have fix stop loss same 10pip
2-if the first order going to profit opening 2* same this order but tp=fist order tp-fix sl
3- traling sl to second order opening place

exampel:
eur/usd
on the first price is : 1.5200
1-opening two orders ( buy@ 1.5200 0.1 lot size sl=10 tp 50 & sell@1.5200 0.1 lot size sl=10 tp=50)
price go to 15210
2-at this time (my sell order will be close & will opening second buy order 0.2 lot size by sl=10 tp=40 and fist order sl traling to 1.5210 )
price go to 1.5220
3-at this time (opening buy order 0.4 lot size by sl=10 tp=30 and two befor orders sl traling to 1.5220)
4-.....
5....
if the price going to 1.5250 all orders will be close by 560$
but at this time our orders sl we only lossing 60$
this method have very best risk

excuse me this expert sl have to using this formul for having profit result on thefix sl have bad result
order sl = ((MaxTrades*MinGS)+SL) - (n*MinGS)
exampel for this info
extern int MinGS=5;
extern int TP=20;
extern int SL=10;
extern double lot=0.10;
extern int MaxTrades=7;
extern int RegularSpread=2;
extern double Multiplier=2;
extern double LotInc=0;
extern double MarginLevelAlert=1000;
we have
first order sl= ((7*5)+10)-(0*5)=40
second order sl= ((7*5)+10)-(1*5)=35
and other sl are
35
30
25
20
15

Thanks.

The previous reply was incomplete.
If the indicator is standard in MT4, it will show up in the normal place. If it is called by iCustom, it will also show up, if coded right.
The following EAs even have the indicators show on the chart window. Study them to learn how:

Hi folks,

I made an EA that calculates daily hi-low between some period, and then place pending orders buystop/sellstop, that will expired in 12 hours.
I run it in GBP-JPY pair (8 pips spread in my broker)

Code:

int ticket, SL, TP; //SL= StopLoss , TP= TakeProfit
int Spacing = 10; // Spacing Pips 
double vAsk = HighestPrice+Spacing*Point;  //  raise/lower 10 pips for OP Buystop/Sellstop , HighestPrice= some highest price  

ticket=OrderSend(Symbol(),OP_BUYSTOP,Lots,vAsk,0,vAsk-SL*Point,vAsk+TP*Point,"Pending Order BUY STOP",20070125,CurTime() + 12 * 3600,Green);

The result, Pending Order Buy Stop was executed, even price did not touch it. I have traced the OP Buy Stop, placed at price 204.08, but it was executed when the price is at 204.00. It seems that Spread factor is involved.
My friend told me that manual Pending Order Buystop/Sellstop is executed without spread factor, but why it's different with placing order by EA ?

So is there any mistakes in my code ?

Thanks in advance.

If your "HighestPrice" is a BID price as they are on all charts, you probably have to add the spread. Any BUY order is triggered by a ASK price.
