Hey,

What are the limits of publishing price feeds to btsx as a delegate?
Can this script be scaled up to provide dozens of price feeds? Or is there a limit?
Eli5 how price feeds work? :S

Cheers

It's dynamic in that you can set a change_min and change_max threshold, when the script polls the prices and seeing a change that fits in the range you set it publishes the new price.  On top of that you can set a periodic time countdown where it will publish the price on a schedule.  So currently I have my script setup to publish the feeds if prices go over 1% and under 50% change and also every 4 hours regardless of price activity.

As far as how many feeds it can monitor and update, skimming the script I see nothing that would limit how many are allowed.  When a price is published it is a separate RPC call with normal fee so the script just runs through the feeds and publishes them one by one when the criteria matches.

Let us know if you need any help customizing the script, it is very simple and just some variables that need changing.

The steps and UI to set it up were surprisingly simple, easy and fast.

Delegate alecmenconi updated to 0.4.12 now.

It looks to me like that sub forum was closed and those thread topics merged into this sub-forum.  I suppose it didn't make much sense to have two BitsharesX sub-forums.

Updated. I've also added the version information to the delegates overview on my site, that way you can get a quick visual overview

Hmm I updated my version registered as "0.4.11-RC2x64" but it highlights the field as red.  I assume this isn't a big issue overall and you likely just coded it to look for a few set strings but is it frowned upon to list the version as verbose as that?  Maybe I should change it to just "0.4.11"?  Not sure what the best practice is here or if there is one established.  Updated client seems to be running smooth though.

Hey svk,

You might already know and be working on it, but it looks like your site's connection to the blockchain is down as all areas appear to be not populated with data.

I tried it from 2 different sources so I don't believe the problem is on my end.

Just a heads up in case you weren't aware.

Thanks.

Hey, thanks for the heads up but like the others are saying it does work, it's just a strange bug related to cross origin sharing, which means your browser is blocking the data sent from my back end since it's not on the same domain as your computer.

My http headers are all OK to handle this, but it seems sometimes it just refuses to work. Will investigate once I find the time.

Thanks for staying on top of things and responding even when it was a false alarm.  I'll know next time to just wait for it to come back on it's own.

Recently I built some code that loads dynamic content on other people's websites, I had some initial issues with CORS for some reason so I defaulted to JSONP and that has worked well, not sure if that could be a possible solution though if you want to do more interaction for your visitors than just GETs at some point.

Thanks for the tip, I considered doing that when I first implemented it but decided to go the CORS way, but in the end I should've just gone with JSONP from the start.

I just switched the site over to using JSONP calls, if you notice you're not getting updates do an F5 to get the new version with the proper API calls!

Nice! You do fast work.  Hopefully that ends up being more stable.

We desperately need to find a way to increase vote percentage.

Agree completely.  This sounds like a great initiative and I hope it's successful in getting more people voting and involved with communicating to their delegates what they want to see.
