iHighest iLowest Clarification

Assume 3 bars: Bar [2], Bar [1] and Bar [0] (Current).

Is the following "stop_low()" function correct to find the lowest low of bar [2] and [3] ?

double stop_low = iLowest(Symbol(),0,1,2,1);

------------------------------------------------------------

Reference:

int iLowest( string symbol, int timeframe, int type, int count=WHOLE_ARRAY, int start=0) Returns the shift of the least value over a specific number of periods depending on type. Parameters:
symbol - Symbol the data of which should be used to calculate indicator. NULL means the current symbol. timeframe - Timeframe. It can be any of Timeframe enumeration values. 0 means the current chart timeframe. type - Series array identifier. It can be any of Series array identifier enumeration values. count - Number of periods (in direction from the start bar to the back one) on which the calculation is carried out. start - Shift showing the bar, relative to the current bar, that the data should be taken from. Sample:
// calculating the lowest value on the 10 consequtive bars in the range
// from the 10th to the 19th index inclusive on the current chart
double val=Low[iLowest(NULL,0,MODE_LOW,10,10)];

iHighest and iLowest don't return the price, but they return the shift of the bar.

To get the lowest low in a series of bars, you need to do:

iLow(NULL, 0, iLowest(NULL, 0, PRICE_LOW, [number of bars], [starting from this bar]));


In your case, you need to do...

double stop_low = iLow(NULL, 0, iLowest(NULL, 0, 1, 2, 1));

ronald raygun,

thanks!

I would like to find the highest high and lowest low between start_time and end_time but EXCLUDING the start_time and end_time bars. I only want to find out the bars BETWEEN the two timings. How do I do that?

Is this the correct code?

datetime start_time = (whatever time you like: StrToTime("YYYY.MM.DD HH:II:SS"));
datetime end_time = (whatever time you like: StrToTime("YYYY.MM.DD HH:II:SS"));
int start_bar = iBarShift(Symbol(),Period(),start_t ime,0);
int end_bar = iBarShift(Symbol(),Period(),end_tim e,0);
double high = High[iHighest(Symbol(),Period(),MODE_HIG H, start_bar-end_bar, end_bar)];
double low = Low [iLowest (Symbol(),Period(),MODE_LOW, start_bar-end_bar, end_bar)];

Does it include or exclude iHighest and iLowest the the start bar and end bar? I need my EA to do the precise measurements. Not one bar before or after.

very good friend , I made a robot in mql4 and I managed to project the fibonacci identifying the iHighest and iLowest, there are days that he gets perfect, but there are days that have a 46 pips difference between what he identified as the minimum of the day about what it really is the minimum. I do not understand this gap, there are days that identifies exactly well above, but there are exceptions that happen this difference, I have even researched and I am making the right code according to my sources, I do not know what could be seen friend. Does the spread impact the price identification in the iHighest and iLowest functions? I attribute the result of these functions to variables of type int, since Fibonnaci's Create Object does not allow double numbers. any help i will be very happy

datetime today = iTime(NULL, PERIOD_D1, 0);
int candlesToday = iBarShift(Symbol(),PERIOD_M15,today);

// 96 count of candles day has in period of 15 minutes
int highYesterday = iHighest(NULL, PERIOD_M15, MODE_HIGH, 96, candlesToday);
int lowYesterday = iLowest(NULL, PERIOD_M15, MODE_LOWER, 96, candlesToday);

double openYesterday = iOpen(NULL,PERIOD_D1,1);
double closeYesterday = iClose(NULL,PERIOD_D1,1);
datetime OpenTime = iTime(NULL,PERIOD_D1,0);
datetime CloseTime = iTime(NULL,PERIOD_D1,0);

int shift=iBarShift(Symbol(),0,OpenTime);
if(Time[shift]!=OpenTime) { OpenTime=Time[shift-1]; }
if(Time[shift]!=CloseTime){ CloseTime=Time[shift-1]; }

ObjectDelete("Fibonacci");
if(openYesterday < closeYesterday){ObjectCreate("Fibonacci", OBJ_FIBO, 0, OpenTime, High[highYesterday], CloseTime, Low[lowYesterday]);} else{ObjectCreate("Fibonacci",OBJ_FIBO,0,CloseTime,Low[lowYesterday],OpenTime,High[highYesterday]);}

double level100= ObjectGetDouble(0,"Fibonacci", OBJPROP_PRICE,0);

double level50= ((level0+level100)/2);
