There is no longer an Ensign IB Beta (primarily for backfill). It has already been released as the official version for IB (mid-December). I use it primarily for futures (Asia and Europe) and it works great but I also use it for IdealPro forex (mainly EUR/USD and USD/JPY) and it works fine for me.
However, I have had tried to chart EUR/JPY and it has been difficult at times to get backfill.
