Thanks Linuxser!

I have never used this statement before and now I shall add this to my collection for future reference. You made my day, and now I can proceed with my logic for my EA.

May God Bless You and give you a Long and Healthy Life!

Dave

This gives me the value at a lowest or highest particular RSI bar, but I also need to find out the bar back number for i.

There is a statement:

PHP Code:


			
Highest_bar = iHighest(NULL,0,MODE_HIGH,BarsBack,StartBar)

that gives me the highest bar back number, but I need a modified statement to work with the RSI. Any suggestions on this??

Hai GURU,

I have problem with my EA, I use buystop and sellstop with TP.
In by backtest, most of times it could execute with no problem but other times it's error INVALID_STOPS (130)
I already check when it's error, my active price and pending position in acceptable range.
What happen ?

Thanks in advance

Try to use NormalizeDouble(price,Digits). Sometimes price of metatrader is not 1.2000 but 1.20020031023012 and the rest of the digits is a problem for metatrader when placing pending order. Use NormalizeDouble and it will be ok

Here is the suggestion:
add your rsi values to an array, and then use ArrayMaximum and ArrayMinimum functions. They return index of array instead of value, so you will know which i is it.

I will try to work with the array.

Thanks

Thanks so much Kalenzo, it's works now.

Solution found!
Hi Coders

I try to insert a function in my EA to choose the trading days.

The function for trading hours works well.

For trading hours i use following:

extern string TradingHours = "TRADING HOURS";
extern bool UseHourTrade = True;
extern int FromHourTrade = 8;
extern int ToHourTrade = 18;

and later after int start:

if (UseHourTrade){
if (!(Hour()>=FromHourTrade && Hour()<=ToHourTrade)) {
Comment("Time for trade has not come else!");
return(0);

But what is needed for select the trading days?

When I define the extern as follow:

extern string TradingDays = "TRADING Days";
extern bool UseDayTrade = True;
extern int FromDayTrade = DayOfWeek;
extern int ToDayTrade = DayOfWeek;

then I have follow two messages:

'DayOfWeek'-variable expected

what's to do?

Somebody can help me?

Thanks for any help

i had a problem , how to make only 1 position open and 2 pending.
let just say Buy and Buystop , Sellstop.
i had an info before from someone in mql4, he use :

if(buystoporder>0 && sellstoporder>0)return(0);

and before that , he use switch(OrderType()).
I am confuse , where do i have to change the code?
i am ended in the buystop and sellstop open several times when i change the code, while if not, it wait until one is trigerred , reach their SL or TP and then make a new 2 pending.

My goal is 1 open and 2 pending, so when the open reach the SL or TP, one of the pending is trigerred, one isnot trigerred will be deleted. and make another 2 pending.

and Is it possible to put magic number in switch() option?

Greatly thanks for your help.
