Recently I found that I can no longer see any chart data for futures calendar spreads, e.g. JPY futures. The charts are simply blank. My TWS bulid is 884.6 and Java version is 1.6.0_05. Anyone else has such a problem?
Just downgraded the Java to 1.5.0_11, the problems still persists. Now I start to suspect the problem is with TWS 884. Could someone add a futures calendar spread (anything) and see if the chart looks ok? Thanks.
