Programming confusion on an EA
I'm trying to grab values from an angle object on a chart (see attached picture). I can get the properties like so: Code:
double angleprice2=ObjectGet("Angle",OBJPROP_PRICE2); double angleprice1=ObjectGet("Angle",OBJPROP_PRICE1); datetime angletime2=ObjectGet("Angle",OBJPROP_TIME2); datetime angletime1=ObjectGet("Angle",OBJPROP_TIME1);
What I can't seem to do is this: Code:
int bar1=iBarShift(NULL,0,angletime1,false); int bar2=iBarShift(NULL,0,angletime2,false);
bar1 is the orgin point. bar2 is what I have in the rectangle in the pic. when I try to get the bar, I get either 65000+ or -1 depending on iBarshift exact.
I'm trying to get the "rise/run" out of the angle so in code, so I can tell where the angle's price is on candle 0.
Any ideas? thanks.

iBarShift() returns the number of any already existing candle (0 = currently forming candle; 1 = the most recently completed candle; 2 = the next one to the left; and so on). I can't say for sure, but I expect that the unpredictable results could be due to your time values being related to candles that haven't yet occurred, i.e. the 'whitespace' area at the right of the chart.

Yep, that's what it is. But, oddly enough, I can get the time value from that point. Maybe there is a way to subract one time value from another.
Thoughts?

different of bars between angletime1 and angletime2 :
PHP Code:
int bardiff = (angletime2-angletime1)/(60*Period());

you can get the value from the object at 0 bar by using
ObjectGetValueByShift("name", 0);

actually, I can't. All I get back is 0.
I've even tried to get back the angle value by setting time1/price1 and time2/price2. And still all I get back is 0.
Here's the code:
Code:
#property copyright "Copyright © 2010, Nondisclosure007" #property link "http://no.link.yet" #property indicator_chart_window #property indicator_buffers 2 double floor[]; double ceiling[]; int init() { IndicatorBuffers(2); IndicatorDigits(Digits); SetIndexBuffer(0,floor); SetIndexLabel(0,"Lower Angle"); SetIndexBuffer(1,ceiling); SetIndexLabel(1,"Upper Angle"); SetIndexEmptyValue(0,0.0); SetIndexEmptyValue(1,0.0); ArraySetAsSeries(floor,true); ArraySetAsSeries(ceiling,true); return(0); } int deinit() { ObjectDelete("LowerAngle");ObjectDelete("UpperAngle"); return(0); } int start() { int i, k, limit, counted_bars=IndicatorCounted(); limit = Bars-counted_bars-1; double varLowMACurrent, varLowMALast, varHighMALast, varHighMACurrent; datetime varTime; for(i=limit; i>=0; i--) { varLowMACurrent=iMA(NULL,0,34,0,MODE_EMA,PRICE_LOW,i+1); varLowMALast=iMA(NULL,0,34,0,MODE_EMA,PRICE_LOW,i+2); varHighMACurrent=iMA(NULL,0,34,0,MODE_EMA,PRICE_HIGH,i+1); varHighMALast=iMA(NULL,0,34,0,MODE_EMA,PRICE_HIGH,i+2); if (ObjectFind("LowerAngle")==-1) {ObjectCreate("LowerAngle",OBJ_TRENDBYANGLE,0,Time[i+2],varLowMALast,Time[i+1],varLowMACurrent);} ObjectSet("LowerAngle",OBJPROP_STYLE,STYLE_DOT); ObjectSet("LowerAngle",OBJPROP_TIME1,Time[i+2]); ObjectSet("LowerAngle",OBJPROP_TIME2,Time[i+1]); ObjectSet("LowerAngle",OBJPROP_PRICE1,varLowMALast); ObjectSet("LowerAngle",OBJPROP_PRICE2,varLowMACurrent); ObjectSet("LowerAngle",OBJPROP_COLOR,Magenta); ObjectSet("LowerAngle",OBJPROP_RAY,true); floor[i]=ObjectGet("LowerAngle",OBJPROP_ANGLE); if (ObjectFind("UpperAngle")==-1) {ObjectCreate("UpperAngle",OBJ_TRENDBYANGLE,0,Time[i+2],varHighMALast,Time[i+1],varHighMACurrent);} ObjectSet("UpperAngle",OBJPROP_STYLE,STYLE_DOT); ObjectSet("UpperAngle",OBJPROP_TIME1,Time[i+2]); ObjectSet("UpperAngle",OBJPROP_TIME2,Time[i+1]); ObjectSet("UpperAngle",OBJPROP_PRICE1,varHighMALast); ObjectSet("UpperAngle",OBJPROP_PRICE2,varHighMACurrent); ObjectSet("UpperAngle",OBJPROP_COLOR,Magenta); ObjectSet("UpperAngle",OBJPROP_RAY,true); ceiling[i]=ObjectGet("UpperAngle",OBJPROP_ANGLE); WindowRedraw(); } return(0); } //+------------------------------------------------------------------+

it works, theres some other problem
tl by angle only uses price1 and time1
paste this in any indy, then create a tl or tl by angle or a hor line, itl return the value of that object at current bar
if the object doesnt exist, itl return 0
Print(ObjectGetValueByShift("name", 0));

Thanks Tom. I tried that a while ago, and it didn't work either. But, I added floor[i]=0; ceiling[i]=0; at the begining of the for loop and now I get the values. I don't know why, but it works.
You can use 2 times and 2 prices to set tl by angle (the manual for mql4 is slightly wrong on this one). One time and price w/ angle is the minimum.
I'm curious when you say it worked. What build of MT4 are you using? I've got build 225 that I'm working in.
