I am from the school of thought that is most prudent, realizing that any company can go bankrupt etc. thus, any time you purchase something,, your entire aamount is at risk.

I keep geetting the inkling that the tradesim manual does not think of $ "risked" the same way. example:
"3. The Fixed Dollar Risk/Volatility Position Sizing Model. In this model a fixed amount of capital is risked on each trade. This should never be confused with the actual position size, which is calculated from the amount risked. This model requires an Initial Stop Copyright © 2000-2003 by Compuvision Australia Pty Ltd.

Page 92"

I am aware that some feel that if one hhas a stop loss on then the stop loss amount is all that is risked, despite frequent busts down through this, gaps etc. others say that the "average amount lost from all losing trades" is the amount risked, etc etc etc.

Please be so kind as to share the tradesim definitions and are different definitions being used at different times in the manual. I used the search function and could not figure out tradesim definition. thank you so much . this will help me be reassured that i am no t fooling myself with results of simulations and that I know what to look for during actual day to day trading , and how i need to set up my systems. regards, geoffrey

Risk means how much risked on each trade. However this is only relevant if a protective stop is used to limit the potential loss of a trade.

TradeSim decsribes risk in terms of a potential loss rather than actual loss.

When using "Fixed Dollar" risk PS model then PS is adjusted so that when a trade goes bad then the loss will average to the fixed dollar amount. (the loss is never the fixed dollar amount because the trade usually never exits right at the stop due to slippage etc)

When using "Fixed Percent" risk PS model then the PS is adjusted so that when a trade goes bad then the loss will average to a percentage of the total capital at the time the trade was taken.

If you don't have a protective stop enabled then the risk will much likely be a lot greater and uncontained.
