This is to post my thoughts about OT 2002 EOD version. Warning : it's a very elaborate rating. Part 1 : First time I came across OT was in early 1999. I use only the EOD version for stocks. Current release is OT 2002 Version 4. OT is imho a very unique program, offering a wealth of possibilities for a technically oriented trader to work with. However, contrary to what Nirvana says, it is not a beginners tool imo. One should have a thorough understanding of how the indicators used in OT work, what OT does with these indicators, how the voting process works and can be influenced and how the various other functions work together in order to get the best out of it. After that objective is reached, OT offers the user a very much organized way of managing his trading. It prospects for interesting signals, helps to evaluate and plan a possible trade, and offers the tools to manage the trade after a position has been taken. Especially the 2001 / 2002 versions offer some valuable tools I missed in the past versions as a multiday swing trader. After working with their 2002 release for quite a while, my previously ambivalent opinion towards OT has changed to a more positive one . I think, a review of this software deserves a bit more room then just a single line or two. Let me just say, that I'm in no way related to Nirvana. I have used and tested several of the higher priced software packages as well as cheap TA software. OT is , among others, still part of my arsenal of a few trading tools I kept after all this testing, while I skipped using most products- simply they didn't fit to my trading style or because of a lack of capabilities. The following expresses my opinion on OT, release 2002 EOD version - used for short-term trading ( 1 day - 3 weeks ). As Nirvana stresses several times throughout their good education files, OT is NOT an automated trading system ! Although all those performance statistics generated by OT might let you think otherwise. Don't trade OT's signals just as they are fired - evaluate thoroughly any trade signaled by OT before you pull the trigger ( as you would probably do it with signals generated by any other trading software, I guess ). Afterwards, use the wealth of tools to manage the trade ( trendline S&R line alarms, 8ths. Tool, S&R, levels, automated P/L stops, portfolio-functions etc.) OT is not a black or grey-box TA-software. The user has access to all of the 120 daily and weekly indicators used by OT. He can change their parameter settings and select & deselect the various system for use in his profile. He can choose from a variety of customizable entry & exit conditions as signal confirmation or as triggers for a trade. The user can opt for delayed trade entries & exits to add a more realistic scenario to the backtesting ( one enters a trade ususally the day after a signal has been fired, not on the same day, since the EOD data wasn't available for backtesting until the markets close ). He can also use customized commission-scales and available portfolio-capital for the backtesting. He can not develop and apply his own new indicators in OT. Thus, OT is certainly not a developers preferred tool ! In OT 2002, all indicator (also called "trading-systems" ) signals can now be used as additional confirmation-filters for OT's generated voted signals. Weekly signals can be used as confirmation for daily signals and the user can determine the level, to which extend and which of the weekly systems OT shall use for this confirmation process, aside from those choosen by OT diuring the backtest-process based on their performance. In addition, one can define stop & delayed entry rules and the type of signals used by selection or customization of the trading model used for each profile ( a profile is the list of stocks / funds etc. you want to let OT work on ) OT comes with a number of pre-defined profiles and trading-models. One can setup an almost unlimited number of own profiles. Since the OT 2001 version, several chart annotation tools have been integrated, among others automatic trendline-break alarms, 8th. tool etc. Fibonacchi and S&R levels, long, medium and short-term trendlines as well as several candlestick patterns are calculated automatically and displayed on the charts ( daily and weekly mode ) Back & Forward testing ( - results ) : Probably the most discussed subject when people start to rate OT. One has to understand the philosophy behind OT in order to make a valuable judgement on OT's usefulness in back and forward-testing. Otherwise, the ( changing ) results may lead to misunderstandings.
