# [EA] Issue with defining high and low of bar where the signal appears

[Deleted]

Hello Everyone,

I try to create the strategy for EA. It is based on simple average from indicator. Strategy which I have already created is below:

```MA_1_t=iCustom(NULL,0,"TEST",4,6);
MA_2_t=iCustom(NULL,0,"TEST2",4,6);

if (MA_1_t > MA_2_t && iWaitFor == PLOTUP)
{
double high=iHigh(Symbol(),PERIOD_H4,0);
double low=iLow(Symbol(),PERIOD_H4,0);
Print ("high=" , high );
Print ("low=" , low );
<missing code>
iWaitFor = PLOTDOWN;
Opn_B=true;

}
if (MA_1_t < MA_2_t && iWaitFor == PLOTDOWN)
{
double high=iHigh(Symbol(),PERIOD_H4,0);
double low=iLow(Symbol(),PERIOD_H4,0);
Print ("high=" , high );
Print ("low=" , low );
<missing code>
iWaitFor = PLOTUP;
Opn_S=true;
}```

The strategy is simple: When two lines cross we have signal. Signal buy is when next bar closes higher then high of bar on which the signal appeared. Signal sell is when next bar closes lower then low of bar on which the signal appeared.

The first issue is that I would like to define the High and low of bar where the signal appears.

The secondly I would like to under <missing code> define criteria opening or closing ticket which I described above.

I will be appreciated for any help.

Thank you for creating this new thread :-)

Are you sure that your iCustom call is correct ?  you are retrieving the value for Bar number 6 from buffer number 4 . . .  is that what you meant to do ?

It works as I expect. It should be from buffer 4 and it is shifted 6 bars ahead. The same effect I have on indicator. I wonder how to point bar under EA where the buy and sell appear. The bar which its close is higher then the high of bar where the signal appears and the same for sell. Below visualization. :)

A shift of 6 does not mean "shifted" it means bar 6 where the current bar is bar 0,  the next bar to the left is bar 1, then 2 etc.  So you are looking at the value for bar 6,  or the 7th bar on the chart going from right to left.  if you want to look a the next bar then that is bar 5.

Can you post your Indicator ?

``` if (MA_1_t > MA_2_t && iWaitFor == PLOTUP)
{

}

if (MA_1_t < MA_2_t && iWaitFor == PLOTDOWN)
{

}```

Those are not crossing,

MA_1_t > MA_2_t is telling that MA_1_t is above MA_2_t,  while MA_1_t < MA_2_t is telling that MA_1_t  is below MA_2_t. You need to check previous bar.

Hello again,

Thanks Raptor for explanation. Your clue gave me another point of view for EA. I decided to modify my indicator. In Indicator I point bar where the signal buy or sell occurs. When signal buy occurs then variable SIGNAL have value 1.0 (double). When signal sell occurs then variable SIGNAL will get -1.0 (double as well). Having this EA doesn't look so complicated:

`SIGNAL = iCustom(NULL,0,"INDICATOR_FOR_TRADING",Avg,Shift,6,0);`

INDICATOR_FOR_TRADING - indicator where sell and buy signal is generated in sixth buffer

Avg,Shift - extern int value which are used to calculate the indicator "INDICATOR_FOR_TRADING"

```   if (SIGNAL == 1.0)
{
Print ("Opn_B=" , SIGNAL );
Opn_B=true;

}
if (SIGNAL == -1.0)
{
Print ("Opn_B=" , SIGNAL );
Opn_S=true;
}```

Please tell me if it is correct or not because it doesn't give me any result :) when EA is executed. EA loads all needed things but sell and buy is not generated. I think that something is wrong with above code. Indicator works great. Thanks in advance.

It would help to be able to see the Indicator code  . . .  for example,  you are using iCustom with bar 0,  does the Indicator re-paint for bar 0 ?  does the Indicator need a few complete bars following the indicated bar ?

``` if (MA[i]>MA2[i] && iWaitFor == PLOTDOWN)
{
iWaitFor = PLOTUP;
CROSS[i-Shift] = 0.0;
f=1;
while (High[i-Shift]>Close[i-f-Shift] && Close[i-f-Shift]>Low[i-Shift])
{
f++;
}

if (Close[i-f-Shift]>High[i-Shift])
{
SIGNAL[i-f-Shift-1]= 1.0;
}
if (Close[i-f-Shift]<Low[i-Shift])
{
SIGNAL[i-f-Shift-1]= -1.0;
}
}```
Above there is an indicator which calculates  value and returns  to buffer.

Is that article still accurate? I noticed another article which seems to contradict it was posted a few years later: https://www.mql5.com/en/articles/1490

The tester in MetaTrader 4 allows seeing not only the tested timeframe, but also other - higher and lower - timeframes. Thus, if we test an Expert Advisor on the timeframe EURUSD M15, we can see the values of the indicators for EURUSD H1 or EURUSD M5. We can also see the maximal and minimal prices of the current zero bar on any available timeframe EURUSD.

Thus, the task of the tester is to model correctly not only the current timeframe, but also all other necessary timeframes. This task is solved in the tester the following way: not only the bar progress on the current zero bar is modelled, but also all other timeframes are modelled the same way. The receipt of each new tick changes the information about the zero bar condition on each timeframe, everything is done synchronously.

All requested timeframes (and not only prices, but also volumes) are correctly modelled. The tester sees the synchronous price progress on each timeframe, like in real life:

Can you copy and paste the contradiction ?  I don't seem to see it . . .
