charger...since I discovered this stuff on supply/demand trading I dont trade without it...on the point of a 5 month old S/D zone that simply means the zone was never traded through or it would no longer show up.Next hit of a long term zone is definitely going to show real power.My charts have 3 key elements...SUPDEM...Zup135 and a standard cloud...pennies and some of the others are working with pennies version of a KISS trading method now...theres several differnt KISS methods..it seems to be working well for them but as for me..I'm very happy with a S/D setup The SUPDEM gives me main supply/demand zones automatically and zup135 gives PRZs...Potential Reversal Zones. I was trying the zuprsi48 but pulled it from chart since I felt it was tough on system resources...kinda liked it tho
