making bars transparent

[Ramon]

I'm trying to hide bars.

I'm using :
BarColor = Color.Transparent;
CandleOutlineColor = Color.Transparent;
into OnBarUpdate

All the bars are transparent , nearly. But the small candle still resists the Ramon legions
What can i do at respect?

Hi Ramon,

Is it the last bar you're trying to make transparent there? This would be controlled with the script's CalculateOnBarClose property. You can set to false to allow for tick by tick updating.

OK. good idea Thanks.
Unfortunatelly I can't do that because i use OnBarUpdate to reset variables in each change of bar. with CalculateOnBarClose to false, variables would be cleared before than expècted.
Any other suggestion?

There's no other way to force updating for the last bar unless you use CalculateOnBarClose = false. If you need to calculate some parts of your script logic with COBC = false and others with COBC = true, this sample can help:

Work. We have conquered rebel candle

I had to change COBC=false from Initialize to OnBarUpdate and only this way works. I don't know if this method makes an unnecesary waste of resources.

I'm doing the right thing? . Thanks a bunch

You only need to set COBC once in Initialize() but if you change in the GUI when you apply the indicator it uses that setting instead.

Hi again.
My scripts were going well until I added a data series

Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Last);
Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Bid);
Add(Instrument.FullName, PeriodType.Tick, 1, MarketDataType.Ask);

then i get the error
error on calling onbarupdate ...... You are accesing an index with a value that is invalid ...

i have commented almost all code and the guilty is

BarColor = Color.Transparent;
CandleOutlineColor = Color.Transparent;

What is the correct use in this context ?
Thanks

This message means you are accessing bar objects that don't exist. Common causes for this and solutions are available here:

In a multiseries script, this means you should exclude all processing until there have been enough bars met for all series. Something like this:

if (CurrentBars[1] < 0) return;

You have to do this for all series, so I would verify your script works as you expect for only one added series before adding any others.

oops. Thanks . I was testing with

CurrentBar > n

and of course didn't work
