OT: Keeping in mind that about the only fixed income I do is callable CDs - treasuries (both coupon and STRIPS) - and munis - and that most is buy and hold - I recommend Zionsdirect ("Bonds for Less") - E*Trade - and Fidelity - in that order. I actually suggest having accounts at all 3 to cross-check prices and inventory. A lot of the prices are the same - and a fair amount of inventory overlaps - because all 3 firms are members of Bonddesk and get most of their offerings from Bonddesk:

Still - it's good to cross-check. Also to check bond trading histories (easy to do on certain websites these days - to see if the offering price makes any sense). There are pretty much no mark-ups on these bonds - you pay commissions based on what you buy (flat $10.95 per trade at Zionsdirect - which is why I like it the best). Still - the ask price from the seller may be good - bad or indifferent. That's where looking at the trading histories comes into play.

I do trade a bit - longer term position trading - mostly in JNK and STRIPS. The commissions on JNK are pretty much the same at all 3 places. Robyn
