Dynamic Text Box

[eros1973ms 10]

I am new in this forum, hope to contribute and learn here.

 

I am dealing with plotting a text on the chart at a fixed position (i.e. upper left corner), based on date/time/price visible on the chart. I am using getappinfo, with aiLeftDispDateTime and aiHighestDispValue, but only the last one works with text_new and set_textlocation. Basically I cant understand how to pass date&time info to text_new separatly as date and time. Any clue? thanks a lot

I clarify a little what I mean with "only aiHighestDispValue works".

 

Code:

vars:

IntrabarPersist date_1(0),

IntrabarPersist time_1(0),

IntrabarPersist price_1(0);

 

date_1 = getappinfo(aiLeftDispDateTime);

time_1 = getappinfo(aiLeftDispDateTime);

price_1 = getappinfo(aiHighestDispValue)-offset_points*2;

 

if symbol = "GS:EUR A0-FX" and (time_1<>time_1[1] or price_1<>price_1[1]) then

print(

symbol,

"data-> ",

StringToDate(DateTimeToString(getappinfo(aiLeftDispDateTime))),

"string data->",

datetostring(StringToDate(DateTimeToString(getappinfo(aiLeftDispDateTime)))),

"ora-> ",

StringTotime(DateTimeToString(getappinfo(aiLeftDispDateTime)))," ",

"string time->",

timetostring(StringTotime(DateTimeToString(getappinfo(aiLeftDispDateTime)))), " ",

getappinfo(aiHighestDispValue):0:4,

setup_count_buy," ",

setup_count_sell,

" ",

getappinfo(aiLeftDispDateTime)

);

 

if date_1<>date_1[1] or time_1>time_1[1] or price_1<>price_1[1] then

begin

id_3=text_new(

date_1,

time_1,

price_1,

"test test test test"

);

value2=text_setlocation(id_3, date_1, time_1, price_1);

end;

 

I inserted also the print command to verify that the calculated values are the one desired, and I can confirm this.

But what I get from text_new is the text is plotted at the correct price level [getappinfo(aiHighestDispValue)-offset_points*2] but at the wrong date/time combination (the text is actually positioned on the first bar of the entire series, not on the first bar displayed).

I have also tried converting the date&time to string and then back to value, but it makes no difference:

date_1 = StringToDate(DateTimeToString(getappinfo(aiLeftDispDateTime)));

time_1 = StringTotime(DateTimeToString(getappinfo(aiLeftDispDateTime)));

 

thanks

aiLeftDispDateTime = Identifies date and time of the first (leftmost) bar displayed on the chart. Returns a DateTime(double) value when called from a chart otherwise returns 0.

 

Here is some simple code that displays the output on the chart. I suggest that you separate out things into small sections of code that you can get to work, with some way of seeing what the output is. This indicator shows what the output of the code is in the upper right hand corner of the screen. In the upper right hand corner, it shows the date and time of the first bar on the chart.

 

var: DateString(" ");

Once 
begin  
Value1 = Text_New( D, T, getappinfo(aiHighestDispValue), "  Begin" );
end;

DateString = DateTimeToString(getappinfo(aiLeftDispDateTime));

Text_SetString(Value1, DateString);
Text_SetLocation(Value1, D, T, getappinfo(aiHighestDispValue) - 0.5);
Text_SetStyle(Value1, 0, 2);

// dynamically adjusts text to upper left corner of chart

 

var: id(text_new(d,t,c,"hello world")), x(text_setstyle(id,0,0)),

intrabarpersist xd(0), intrabarpersist xt(0), intrabarpersist xp(0);

 

xd=juliantodate(intPortion(getappinfo(aiLeftDispDateTime)));

xt=minutesToTime(fracportion(getappinfo(aiLeftDispDateTime))*24*60);

xp=getappinfo(aiHighestDispValue);

text_setlocation(id,xd,xt,xp);
