Trying to write on chart. Please Help.

Brijesh Kuttan 2020.09.01 18:22

I am trying to print the high of a bar 10 points above the high of the bar for last n bars.

Here is my code. I am not getting this to work. Can somebody please help me with this.

I am using X=High[a] as an example here. What I want to do is to print a value(integer type).

Please help. Thanks in Advance.

I have no idea as to how to do it. Can you please help me with it?

William Roeder 2020.09.01 18:51 #3

All names must be unique.
You can't use an as-series index in names as they are not unique. As soon as a new bar starts, you will be trying to create a new name (e.g. "name0",) same, existing, previous, name (e.g. "name0" now on bar one.)

Use time (as int) or a non-series index:
```
#define  SERIES(I)   (Bars - 1 - I) // As-series to non-series or back.
```
Place the object above the candle. Not above the current candle.

William advice is more sensible..time is better

{
         Vertical_Offset= Point*20;
         ObjectCreate("data"+a, OBJ_TEXT, 0, Time[a], High[a]+ Vertical_Offset);
         ObjectSetText("data"+a,DoubleToStr(X),10,"Times New Roman", Red);
         ObjectSet("data"+a,OBJPROP_ANGLE,90);

I did this and it gives me the required output. Thanks

please follow William's advice..you'll avoid future problem..use time as data name concatenation

Made a few changes.

Thank You for your reply. Sardion too is suggesting me to follow your advice. However, I am an amateur programmer.

So I am finding it difficult to understand what you are saying. But, I will go through what you have said.

Thank You,

Not if you call original code a second time. Ignored #3.1 and #7
Use of ObjectsDeleteAll is not recommended. Your code should only delete what it creates. This will likely create problems for you in the future.
For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.
