[BUG] Indicators cannot subscribe to data source that is already consumed.

[n1s]

Bug report

I tried to add a few indicators that track premium across exchanges. It seems that if those indicators consume the same source data the second indicator will have not access to the subscribed market data (the data will be 0).

See screenshot.
Correct sources are added.

Checklist

• I provided a clear and concise description of the bug (see both sections below).
• I documented the issue with screenshots.
• I have attached an [export of my Aggr database] the issue.
• I checked my browser's console output for errors and included it in the issue if any.

Description of what the bug is

• Environment: aggr.trade
• Version: [v3.7.0]

Steps to reproduce:

Add two indicators as follows:

Indicator 1

var exchange = 'BINANCE'
var premium = source(close, exchange=exchange, type="perp") - source(close, exchange=exchange, type="spot")

line(premium, title='binance')

Indicator 2

var premium = source(close, exchange='BINANCE', type="perp") - source(close, exchange='COINBASE', type="spot")

line(premium, title='crossEx')

Indicator 1 will display data correctly.
Indicator 2 will have no data for binance perp so it will displays high negative number from coinbase only.

I don't know where you got those scripts but in your indicator 2 type="crossEx" doesn't match with anything in this app
In the source() function, the type option can be either "spot", "perp", or "futures"
Let me know what chart you wanted to produce i can help

thanks for the quick reply. Sorry my fault. Indicator 2 meant to be as follows ( I edited initial post )

var premium = source(close, exchange='BINANCE', type="perp") - source(close, exchange='COINBASE', type="spot")

line(premium, title='crossEx')

The remaining stays as it was. And the issue for me persists. My aim is to draw premium across different pairs and/or exchanges using few different indicators.
Possibly, too replicate, you might have to add third indicator with the same logic. It's just required to have one data source(exchange+type) consumed multiple times in different indicators.

Thank your your support <3

I see, you can't do that:

var premium = source(close, exchange=exchange, type="perp") - source(close, exchange=exchange, type="spot")

line(premium, title='binance')

It won't interpret the indicator variable (that can change) as a argument for the source function (that can't change throughout the script execution.
your source() is just translated to the results sources that match your filters (type perp, exchange= ?) once before script executions.
Can only use indicator options (which are static) as param of a source function (ex: source(close, exchange=options.exchange, type="perp") ) or specifying as a string (ex: `source(close, exchange='BINANCE', type="perp")

Ok I see. However I think this still doesn't work, If I have two indicators in

var premium = source(close, exchange='BINANCE', type="perp") - source(close, exchange='BINANCE', type="spot")

line(premium, title='binance')

And

var premium = source(close, exchange='COINBASE', type="spot") - source(close, exchange='BINANCE', type="spot")

line(premium, title='crossEx')

I have no data for one source (binance perp it seems this time)

@n1s is this resolved?
