KwikPOP was originally developed on MetaStock then for some reasons (I think the main ones were MetaStock poor ability/versatility in managing RT data and its too high system-resource requirement) they decided to discontinue it in favour of other charting software version... first TradeStation and eSignal and more recently AmiBroker and NinjaTrader.
Anyway you can grab a copy of the last (MetaStock) version on the 2nd-hand market or somewhere else then if you like it I think you can develop almost all the new current indicators rather easily.
Good luck.
