I would like to ask how ET people trade using bollinger bands?
I read in a book by Bollinger that there is a frenchman (maybe his name is cahen or cohen?) who has found various ways to trade them, but bollinger did not elaborate more. I was not even sure whether bollinger himself makes anymoney with them. He seemed to dodge the issue in the book.
This is what I have:
Trend following system: Simulated trading using 30 years IBM stock daily closing price data, $ 100000 initial capital and 5 % risk. This method buys if closing price value is greater than the 60 day moving average value plus 2 standard deviations and sells if closing price value is less than the 60 day moving average value. Position size = (5 % of account equity) / (10 x 20 period average true range). Long trades only. Slippage is assumed to be 0.5 %.
Number of trades 54
Profit after subtracting $ 10.00 commission, slippage per transaction: $ 195366
Greatest draw down is 0.1076 (10.76 per cent).
Cumulative Annual Growth Rate (CAGR) is 6.51 per cent.
Instantaneously Compounding Annual Growth Rate (ICAGR) is 3.61 per cent.
Annually Compounding Annual Growth Rate (ACAGR) is 3.68 per cent.
Information Ratio is 0.35

Buy Low Sell High system: Simulated trading using 30 years IBM stock daily closing price data, $ 100000 initial capital and $ 5000 risk per trade. This system buys if closing price value is less than the 10 day moving average value minus two standard deviations. Position is sold if closing price value is greater than the 10 day moving average value plus two standard deviations. This system stops a loss at $ 5000. Long position trading only.

Another Buy Low Sell High system: Simulated trading using 30 years IBM stock daily closing price data, $ 100000 initial capital and $ 5000 risk per trade. This system buys if closing price value is less than the 10 day moving average value minus 0.5 standard deviations. Position is sold at session opening 4 days after purchase if there is a profit or after 8 days. Notice the logical problem, there is no way to know what the opening price is until after it is reported. Slippage estimated at 0.5 %. Long position trading only.
Number of trades 579
Total profit $ 200272
Profit after subtracting $ 10 commission per trade: $ 194482
Greatest draw down is 0.0814 (8.14 %)
Cumulative Annual Growth Rate (CAGR) is 6.29 per cent.

These simulations generally do not employ all available capital. I observe large amounts of cash remaining in the account as trades are simulated. The risk level used in these simulations is 5 %. I consider use of 5 % risk per security to be unsafe. Trading a number of securities in a portfolio and using lower risk levels might show greater returns and lesser draw downs.
