System 1: Enter long on 20 period donchian channel breakout to the upside, short opposite. Exit long when 10 period donchian channel low is crossed. Exit short when 10 period donchian channel high is crossed. System 2: Enter long on 55 period donchian channel breakout to the upside, short opposite. Exit long with 20 period donchian channel low is crossed. Exit short when 20 period donchian channel high is crossed. If you get a signal for System 1, but the previous System 1 signal was profitable, then you don't take the current signal and instead wait for a System 2 signal. Dunno why that's the rule, but that's the rule. So for example: System 1 entry = stopped out for a loss. Then you get another System 1 entry and you can take it. But: System 1 entry = win. Then y ou get another System 1 entry. You cannot take it cuz the previous System 1 entry was a win. The rules for adding to winners are like... take the 20 period ATR and add one more unit every time price goes up (in a long trade) or down (in a short trade) by the value of the ATR. Ok so like 20 period ATR is 2 and you enter at 100, that means your next add would be at 102, and 104, and 106, up to a maximum of 4 "units." Stops: twice the ATR below a long position or above a short position, and this should not exceed 2% of your account (so you'll have to play around with your position sizing). Every time you add another unit (cuz price moves up by ATR) you move your stop by 1/2 the ATR. Yes, this means that even after a fully loaded 4-unit position, your stop will still be BELOW your original entry price. No locking in profits. This takes BALLS. But this system counts on hitting the occasional home run, so no locking in profits and getting stopped out. So anyway, the Turtles did this on the daily charts. But charts are fractals, right? Timeframe doesn't matter. So theoretically this should work intraday. Except people say it doesn't work anymore, or at least System 1 doesn't work anymore. Beats me. How were the markets in 1983 or whenever they were doing this? Like everything else, seems like this would be awesome in a trendy market and worthless crap in a choppy market. Someone do this or code it and backtest it. I saw it once backtested on Forex but it was from an EA vendor so I don't trust it.
