Thanks to yesterday's disappointing Non-farm Payroll numbers the greenback fell and my troublesome sell limit order at European broker ActivTrades finally got filled. Consequently my new Interbank MetaTrader 4 micro-lot account with them is now fully funded, and open for business. As you can imagine, I have had one or two long discussions with ActivTrades over the last couple of days. During the course of those they pointed out to me that enough of their liquidity providers are now willing to quote and fill a 1K trade that it had now proved possible for them to introduce micro-lots on their "Straight Through Processing" (STP for short) MetaTrader Interbank accounts. When I enquired what "enough" meant in this context, the number three was mentioned. Unlike their Standard account, there is no "averaging algorithm" inserted by ActivTrades between you and the banks on their Interbank account. Instead they just add a bit to the spreads they are quoted, since they have to earn a crust somehow just like the rest of us.
I've had a live account with London based broker ActivTrades for quite a while now. It's one of their "Standard" MetaTrader 4 accounts. I opened it because it offers micro-lots and lots of exotic currency crosses, along with a wide range of non-forex instruments, including stock indices, gold, oil and other commodities too. That combination is a little hard to come by at other brokers. It is slightly old fashioned however, in that it still uses 4 decimal places and fixed spreads. 2 on the FTSE 100 and 3 on GBP/USD for example, most of the time at least.
