Short and Sweet I hope
1. TradeSim Basket Testing ability!!! :D
{Excepts every possible trade signal from your trading system without rejecting anything.
Then it display the results & allow the users to select out of an unlimit number of security which ones have preformed great in the past and are more then likely to preform great in the future with your current trading style. }

2. Real world simulation of my trading system over a portfolio of security. {Very Hard to do with metastock backtester}
The backtester will only except trades that meet your predefined trading rules regardless of the trading signals being created by Metastock and reject other securities if they don't meet your predefined trading rules.

Say if metastock created 7000 entry signals for buy & sell over a 10 year period. Depending on your rules and portfolio size the system may only trade 2400 of those signals. Acting more like you would if you had traded it in real life. Because we don't take every trade metastock gives us because of things like risk, capital, current draw down & portfolio heat. All of these things are covered in detail with TradeSim

I love metastock but every software has its limits. With TradeSim it gives you that serious extra edge you need in the market place. I have been able to get right down to the bottom of a ton of so called trading system with this tool. I've purchased & returned alot of system based off the results I got from TradeSim. I've found the best system is the one I encode for myself and test with TradeSim.

You can't find a better back tester then TradeSim I've looked high & low. If you find a better one please don't tell me about it the first jounry to find TradeSim was long enough I don't want to search anymore Hahaha.

Serious thou read the user manual twice and then try the 30 day trail. Support alway email you back if you get stuck but in my opinion Metastock & TradeSim go together like a hand and a glove. Great combination!!!

If you want to see some of the charts I believe Jose uses some on his website to show his real world trading record.

:) Bottomline this backtester keeps me in the money and deep in the black.
