It would be great that if in addition to pips gained / day in the twitter option that you could add the percentage gain on the day. For example I just closed a profitable arbitrage between the NZDJPY and EURNZD. That said the pip value on the EURNZD is about 70% of that of the NZDJPY. So... it shows a negative pip count (which is true) but the trade was profitable. In addition unless a person is using a fixed lot size across all pairs, the pip count is kind of irrelevant. People using volatility based position sizing or the kelly criterion or the one that scares me... Martingale. All of these people's results as far as their twitter followers are concerned, are skewed. I'm sure myself and a lot of others know and believe that daily gains are far more significant than a pip count.
I'm guessing it wouldn't be terribly difficult to implement as all of the data you need is most likely stored in an SQL database that you pull to present the data on each and every one of our stats pages.
