I have modified two scripts to show the Jake Bernstein Moving Average Channel (MAC) along with the Williams A/D on the same chart. MAG Silver had a bullish trend on daily and weekly MAC. MAG Silver a an excellent way to bet on a rebound in silver - they have a world class mine in Mexico. Weekly MAC buy at the bottom of the channel $17.70 (sell at top of the channel $19.04). Also trades on the Toronto Stock Exchange under the same symbol, MAG.
