You misinterpret my point. I am 14 years in the red partly because I have not spent enough time in the demo room and have used real money to try to learn this trading game.
Backtesting should always be your starting point in designing your trade strategy especially with today's technology at. Next, paper trading / demo trading should always be for putting that backtested trade strategy into a trading plan along with learning how to use your broker trade execution platform...learn how to use your charting platform...all in a simulated trading environment.
Yet, be very careful...that paper trading / demo trading should only be long enough until you've master your broker trade execution platform and all other software you're going to be using while putting that backtested trade strategy into a viable trading plan.
Next, if the backtesting has positive results...you then move into real money trading with a very small position size and this can last months while for some may be years before any normal position size trading can be used. You stay in the backtesting mode until you designed or find something that gives you positive results...even if it takes months or years.
A trade strategy is just one chapter in the trading plan.
The phase where you move from backtesting your trade strategy into a trading plan is where most get lost or stuck. Unfortunately, many then move into the paper trading / demo trading
without a viable trading plan and then they then move into real money trading...resulting just another failed trader or as you call it...in the red for many years.
Those that's been at this consistently for many years trying to get green...they've mixed up the above so that its a mess. For example, trading with
real money via a trade strategy or trading plan that has not been backtested nor paper traded (demo traded).
P.S. Backtesting doesn't imply you use the results of someone else as truth or viable. In contrast, you must backtest the trade strategy
yourself in your trading plan to see if it merits spending any kind'uv time in paper trading / demo trading...all prior to any real money trading.
Simply, do
not use paper trading / demo trading as a substitute for backtesting...you'll just end up spinning the wheel for many years.
