How can I set up a whitelist and blacklist to only forward certain messages?

[RollinCajun]

I'm trying to filter messages that contain a certain text string and ignore all other messages. I only want the certain messages forwarded but I'm unsure how to do it. I've tried several things and it's not working for me.

I want to forward only messages that contain US30 SELL or US30 BUY in the first line of the message.

The format of the messages are like this.

🚨US30 SELL

ENTRY:  33350

SL:  33410

TP:  33300
TP:  33250
TP:  33200
TP:  33150

I tried using this in the whitelist but no messages are being forwarded so it's not correct.

'(.US30 SELL.)'
'(.ENTRY:.)'
'(.SL:.)'
'(.TP:.)'

There are other messages posted in the group talking about other things but I only want these specific ones forwarded to me. I could use some help thanks!
