Futures - Measure and compare volatility in USD

Dollar value (syminfo.pointvalue) is wrong in Tradingview for the below listed futures, where the price is in quarters of cents. So this is a dirty fix.
For example ZC (Corn) says syminfo.pointvalue = 5000 (syminfo.mintick = 0.13), which gives you (ATR = 6) volatility 30,000 USD instead of the correct 300 USD.
For all other futures is used the default syminfo.pointvalue.
