I find the Fidelity trading algorithm used to calculate margin requirements to be useful in trading. Trade station not so much.  For example on Thursday night the algo changed the margin requirements for DRD from 30 to 40%.  It is smarter than I am. I carefully checked everything I could find on DRD and was clueless. I sold DRD and other long positions in the miners after the opening hour. I saw the same dismal charts in the miners like others have posted here. For my trading portfolio I am 90% cash and 10% long the November 50 puts on the GDXJ. I have this weird feeling that we are going to revisit the March lows. I was all the volume on friday and its going to be very difficult for me to exit unless they go into the money.
