General Discussion · Justification of short term trading

I've enjoying doing a little short-term trading, but I have an ethics question: does it have a beneficial role to play ? I think a free market is good. I also think long-term investors in the stock market help supply companies with capital to grow. What about short -term trading? Does it serve a purpose -- perhaps to make for an efficient market? I've often heard that we are just people taking money from each other, but I wonder if there is more to it than that.

Folks, can you really win at this? I've done backtesting on about 15 filter ideas, and have yet to show a profit. I'm wondering if finding a wonderful entry criterion is just not possible. Maybe one just finds a mediocre entry criterion, and then does a superior job managing the trade?

Anyway, for backtesting, here are my parameters...

Timeframe Jan 25 2011 thru Jan 25 2013
Take Profit 2%
Stop Loss 2%
Min days held 1
Conditional entry at Open * 1.005

and here are my "best" performers!!

G/L is -7.3 % for: while candle for two days, both candles no bigger than 1% of the price. ma(10) approaching ma(30) from below in last 2 days

G/L is -.8 % for: white candle for two days, price 5% below ma(200), trading in channel for 20 days, RSI below 50

Do you get better backtesting results than this? Do you have superior filters, or better backtesting parameters? Or, do you get the same mediocre backtesting numbers that I do, but with real money, you just manage your trades a whole lot more clever that 2% take profit, 2% stop loss?

Is is possible to have an entry condition dependent on the backtest's most recent sell? For instance, for SPY I would like to take profit at 5%, and stop loss at 5%. I would like to buy when the price moves 2.5% above my most recent SPY sell -- or 2.5% above any intermediate low point since my most recent sell.

Thank you Four. It worked and I learned from it.

Would it be true to say the backtesting results are worse than you would get in real life? The reason being that the exit price does not use your stop loss or trailing stop loss. Instead, it uses the next day open. Assuming your stock is decending, the next day open will usually be lower than your stop loss point.

I hope backtesting is pessimistic, else I have a loooong way to go before I come up with a winning strategy.

I'm trying to find stocks that have perhaps formed a base, and are starting to turn upward. I have:

close increasing for 2 days and price 3% below ma(200) for 9 days

...but the "for 9 days" must not be the right syntax, because it does not have any effect.

I tried "trading within 9 day channel". This worked, but I don't understand how they calculate the 9-day channel. How wide of a channel is it?

There is a User Guide for SF, but it does not cover the backtesting module as far as I can tell. Is there a document for Backtesting?
