I have a RUT iron condor for februari today's profit is only 25 dollars. the greeks were yesterday: delta = 2 gamma = 0 vega = -30 theta = 4 Today RUT went up 3.6 points, and the RVX went down 2.12% that would suggest a (2x3.6+30x2.12+4) = 75 dollars profit. are these calculations wrong ? or are the greeks wrong ? (they are from IB's risk navigator) or are they useless.
