REDIPlus users.... let us hear the good, bad and the ugly for SLK's REDI
Good Order entry,bad data feed. When I used RediPlus, you could not chart the Nasdaq Composite intraday, but you could chart the Naz 100. However, the minimum time frame was 5 minutes and the feed was always slow and often interrupted.
It was common that the 5 minute bar on the Naz index would not update for10-15 minutes. Incredible, and they were proud that they had charting features.
I don't know now how the Redi order algorithm operates with SuperSoes, but before SuperSoes, Arca gave better fills.
SLK, however is the king clearing firm. Their short list is non-pariel.
I use RealTick now, and am happy with it.
