How to Plot Text Characters on a Chart

[[Deleted]]

Hi.

I'm working on some indicators where the basic display idea is just to mark certain bars.

I'm able to mark the bars with DingBats (graphic symbols) fine.

Is there a way to mark the bars with normal alphanumeric letters (lower and/or upper case) in the same fashion?

ObjectCreate() 1 of the Object Tipes is OBJ_TEXT

Thanks, I was able to work with that.

Below (and attached) is a simple implementation of marking up and down bars.

This is working for me, but as I am new to MT4, if anyone has any comments about the basic approach or code arrangement, they would be welcome.

//#property indicator_separate_window
#property indicator_chart_window
#property indicator_buffers 2
#property indicator_color1 LawnGreen
#property indicator_color2 Red

// Bring in ErrorDescription(), among others.
#include <stdlib.mqh>

//---- input parameters
// None

// Variables

color UpColor = Cyan ;
color DnColor = Red ;

int start()
{

int idx, first_idx, jdx, limit, counter, loop, BN, err ;
bool c1, c2, c3 ;
int Counted_Bars = IndicatorCounted();

// General error checks
if(Counted_Bars < 0) return(-1);

//---- force re-processing of latest bar (just in case ...)
if(Counted_Bars > 0) Counted_Bars--;

first_idx = Bars - Counted_Bars - 1 ; // Index of the first uncounted - we will start processing here, decrementing with each pass
idx = first_idx ;

err = GetLastError();
if( err == 4002 ){
Print( " Time[idx]: " + TimeToStr(Time[idx], TIME_DATE|TIME_SECONDS) + " idx: " + DoubleToStr(idx, 0) + " Before loop error(", err, "): ", ErrorDescription(err) );
return(-1) ;
}

// This loop runs from a higher numbered index down thru 0.
// In terms of the OHLC arrays, this is from past to future.
//
while(idx >= 0){ // Loop for uncounted bars

//Print( " Time[idx]: " + TimeToStr(Time[idx], TIME_DATE|TIME_SECONDS) + " idx: " + DoubleToStr(idx, 0) + " Loop top" );

BN = Bars - idx ; // BarNumber with low count at left of chart

if( Open[idx] < Close[idx] ){
// bool ObjectCreate( string name, int type, int window, datetime time1, double price1, datetime time2=0, double price2=0, datetime time3=0, double price3=0)
ObjectCreate("" + idx, OBJ_TEXT, 0, Time[idx], Low[idx] );
ObjectSetText("" + idx, "U", 10, "Arial", UpColor);
}

if( Open[idx] > Close[idx] ){
// bool ObjectCreate( string name, int type, int window, datetime time1, double price1, datetime time2=0, double price2=0, datetime time3=0, double price3=0)
ObjectCreate("" + idx, OBJ_TEXT, 0, Time[idx], High[idx] );
ObjectSetText("" + idx, "D", 10, "Arial", DnColor);
}

idx--;

} // end of: while(idx >= 0)

WindowRedraw() ;

return(0);
