Trade Pulse is currently the best trade script around imo. However, it is rumored that TradeX will overtake all existing trade script to date. The creator has already announced that it is 2,5x faster in processing and tracking than Trade Pulse is.
TradeX by JMB Soft is sheduled to be released within a couple of weeks. The first release date was set to January, but that date has been delayed now. However, Jeremy announced that it is a matter of weeks, not months. Looking forward to the beta release. It will be a super-fast tracking and trade script with never-seen-before features that are not implemented in any trade script on the market. Stay tuned.
Edit: The trade script won't need a database, nor cron jobs to run.
