Raw I1 experienced a lead interval during the Japan quake starting at 7 days and gradually declining. It should be 4 trading sessions at this time. Counting Friday as a session then today was top day. Four actual trading sessions pinpoints tomorrow.
Here is the 30-day I1, indicating a peak either tomorrow or Wednesday.
Silver displays an ending candlestick. PM1 ideally peaks Wednesday, but silver hitting $50 brought a lot of selling. I'm currently short from 47.92 and hold ZSL.
