It relates to the stock selection process by which I select stocks to trade on any particular day.

I have a "watch-list" of 15 stocks which I update every weekend based on various parameters.

My system allows for a maximum of 2 trades per stock per day over 2 trading sessions - afternoon and evening.

Therefore theoretically, I could do 30 trades a day.

In reality I aim to do a maximum of 6 - over the course of the 2 sessions ( afternoon and evening ).

I select 3 stocks per day from the 15 for trading. The selection process is based on a points scoring system from the results of paper trades of the 15 stocks. The process takes into account number of winning trades, number of losing trades, number of winner points, net profit, reward to risk ratio and ATR to price ratio - from the past 5 trading days.

My paper trades allow for plenty of slippage and throw out a winning rate of 85% once a trade is entered. Percentage of " no trades" due to entry criteria not being met is around 10%.

So, all very good or so I thought.

The problem is that I am either just plain unlucky or I am missing something because as soon as I select my 3 best performing stocks and enter real trades, I find that they invariably become losers.

Is the flaw that, I am picking the stocks which have recently performed beautifully and are now due a loser or is there a fundamental flaw in my selection technique ?

I would be grateful for suggestions.
