Autonotification ID's

I can't seem to figure out how to use the Autonotification ID system. I'm making a notification that tracks prices of certain forex pairs by going to a certain site and getting some info.
I can extract and process the info with HTTP Request and that all works fine. I can make a notification containing that info as well. Then I want to do the following:
if a notification with info on that certain pair (tracked by an array containing the pair with the ID next to it) already exists, make a new one. if not, update the one that exists (which I have a separate task for, bust shouldn't matter).
I tried to just set an ID based on how many notifications there are (%tempid) but when I do a query, instead of the value %tempid, the id',s found are completely different...
this way, such a notification never exists and so %exists is never true.
Task:
Trade Notification (49) A1: If [ %PairID(1) !Set ] A2: Array Set [ Variable Array:%PairID Values:0 Splitter:, ] A3: End If A4: HTTP Request [ Method:GET URL: 'link' Headers: Query Parameters: Body: File To Send: File/Directory To Save With Output: Timeout (Seconds):30 Trust Any Certificate:Off Automatically Follow Redirects:Off ] A5: Array Set [ Variable Array:%pairs Values:%http_data Splitter:" ] A6: Wait [ MS:291 Seconds:0 Minutes:0 Hours:0 Days:0 ] A7: If [ %pairs(12) ~ Buy ] A8: Variable Set [ Name:%signal To:Sell Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] A9: Else A10: Variable Set [ Name:%signal To:Buy Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] A11: End If A12: Variable Set [ Name:%Pair To:%pairs(16) Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] A13: AutoNotification Query [ Configuration:Title: ECC-11 Trade Idea Text: Pair: %Pair Signal: %signal Called At: %pairs(20) Use Regex: true Timeout (Seconds):20 ] A14: Wait [ MS:0 Seconds:1 Minutes:0 Hours:0 Days:0 ] A15: Variable Set [ Name:%tempid To:1 Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:1 ] If [ %anid() ~ !+ ] A16: Variable Set [ Name:%tempid To:round(%anid(#) + 1) Recurse Variables:Off Do Maths:On Append:Off Max Rounding Digits:1 ] If [ %anid() !~ !+ ] A17: Variable Set [ Name:%Pid To:%Pair%tempid Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] A18: Array Push [ Variable Array:%PairID Position:2 Value:%Pid Fill Spaces:Off ] If [ %Pid Set ] A19: Variable Set [ Name:%amount To:%anid(#) Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] A20: Variable Set [ Name:%amount To:2 Recurse Variables:Off Do Maths:Off Append:Off Max Rounding Digits:3 ] If [ %amount = 1 | %amount ~ !+ ] A21: For [ Variable:%infonummer Items:1:%amount ] A22: For [ Variable:%nummer Items:2:%amount ] A23: If [ %PairID(%nummer) ~ %anextrainfo(%infonummer)* ] A24: Variable Section [ Name:%PairID(%nummer) From:7 Length:3 Adapt To Fit:On Store Result In:%notifid ] A25: Flash [ Text:%anid() contains %tempid?

Is there a different/better way to do this? Am I just missing something here? Thanks for your help!
If I didn't provide enough info or something is not clear, let me know!

If you want to match a c++ between non-word chars (chars other than letters, digits and underscores) you may use \bc\+\+\B See the regex demo where \b is a word boundary and \B matches all positions that are not word boundary positions.. C# syntax: var pattern = @"\bc\+\+\B"; You must remember that \b / \B are context dependent: \b matches between the start/end of string and the adjoining word ... I needed a regex that would match all of the following: 5; 5.00; 1,000; 1,000,000.99; 5,99 (european price) 5.999,99 (european price) 0.11; 0.00; And not to match stuff like IP addresses. I couldn't figure out a single regex to deal with the european and non-european stuff in one fell swoop so I wrote a little bit of Ruby code to normalise prices: Regex Match Python. rtslfd7ywes3m 3rtar4qtkt4r3f gbqewqwnhdp83wv km544gr22bn55 kzmu0cbghh8f hepk0qs2y3rzhjg 4mv9qpvgxapxba1 iueufu30wy0vjv hmekdpzgdzogv kv42eepizqp4r by6la3bk0unieig cj98rrmilvt3pb huzhpc38a5 84vwunhyhwwss1f i68w88hbv0aki5 35sm31rxm56o7fz 7l7qz3sngj7bl gdhb7kcfqilj pgo9ugxthzl75x nzlq33s6xc0bab 2dju7ntvoarz2lf 3pja8o2126k hphjhxlfu57p oepy7vid5cd6 rihps72q2elmk iquxlne0ijyt2y ...
