personally i found paper trading very good at detecting flawed strategies , after you work out why that strategy failed , you are a little wiser and still have the wallet undamaged@Sdajii
Re paper trading.
I agree if you look at the scenario of paper trading $1000.
However, he could and should use multiple strategies and multiple amounts.
He will gain a wealth of knowledge if he trades all of them at the same time.
Each will trade differently and he can run multiple ideas
He needs to expand his thought process.
Mind you if he is serious he would have developed multiple Positive expectancy
strategies which he would be paper trading.

i did try a little 'channel trading '
that is set a target target entry price for a stock that seems to be trapped in a ( reasonably ) wide range , and selling at a pre-determined price ( or above )
stocks chosen ( at the time ) were WHC , BPT , QBE , and SUN
while i am currently in profit on all 4 stocks , i deem WHC and QBE a success ( for a while ) and BPT and SUN as failures as they dropped into the 'buy range' rose to the 'reduce range ' but never ( so far ) came back to the buy range ( so i could buy and reduce again
please note currently all four stocks are well above my 'buy range ' ( so are NOT current recommendations )
this strategy is very crude and you need a LOT of patience ( it took three years to get my entry price in BPT ) and reducing/selling is merely at the whim of the market ( it could happen any time ) ( or never )
chances are you will not like the waiting involved in this strategy
Taking an idea and paper trading it to determine positive expectancy is highly unlikely to be beneficial .Re paper trading
I used paper trading to test my theory whether X strategy would have a positive expectancy and how I could slightly tweak if need be before live trading. But I found just because a system may have a positive expectancy for you in paper trading doesn't mean it will have the same PE when traded with live money. Once your psychology is in the mix, that's the REAL test IMHO.
I will check it out, thanks!Taking an idea and paper trading it to determine positive expectancy is highly unlikely to be beneficial .
You need good systems testing software and the ability to test your ideas.
You should have a set of conditions to enter
A set of conditions to exit
A risk contingency
Correct position sizing To name a few.
But
There are other options.
There are systems that have tested positive expectancy and publicly available.
In Nick Radge’s book un holy grails there are 3 or 4 in there. Including on of mine “ Techtrader” I trade a hybrid method in my super fund. You’ll also learn what you need to know and WHY you need to know it. The book is still available on line.
Nicks in Bordeaux at the moment but Zac is in control just contact “ The Chartist” Google it
There are sites where you can lease systems.( never done it or know anyone who has )
Systems trading is specifically designed to negate your psychological interference.
If your suffering from PI then you don’t have a complete understanding of what you’re trying to achieve.
Fair enough mateMy reply applies to any sort of hand trade review past or realtime
I will check it out, thanks!
With regards to paper trading I was actually meaning back testing looking back at past history to see how my set of rules and risk parameters would have performed. I'd take my strategy and look back for a period of time with say a sample of 200 trades.. and see if there was any edge.
I think I mixed up that with the term paper trading.
Thanks for the advice and caution, much appreciated. The strategy I've mostly been trading has a success rate of approx 35% but my average RR is approx 4.1. over the last 7 years I've been consistent so that's all I can go off. Who knows, my next 7 years may take all my gains. I find if unlikely because I'll modify my risk management if I have streaks off losses. But that could be just a slower death.One thing to be careful of when paper trading, especially retrospectively (testing it in a previous timeframe) is that you can end up with a system which works really well in one market condition but won't generally work. My first attempt at this, as a teenager decades ago and about 10 years before I ever actually made a trade worked very consistently because it basically said if x then y happens, z will happen. I tested it with dozens of companies and it had about a 90% success rate with very small losses on the other 10%.
Unfortunately, all I had been doing was recognising a pattern which happened to have played out on the macroeconomic scale, so almost all large companies were following the same pattern simply by following the market. That being the case it was never going to have any value in any time other than in the couple of years prior to when I came up with the model, making it useless. This was a good example of pseudoreplication, the first I ever became aware of, but something I learned all about a few years later at university.
