just like with the NMA system if you want to do some backtesting and define both buy and short you also have to define the shortprice, like:
SellPrice = ValueWhen( Sell, C, 1 );ShortPrice=SellPrice;
BuyPrice = ValueWhen( Buy, C, 1 );CoverPrice=BuyPrice;
these type of systems just don’t work because of all the profit will be eaten up in directionless/whipsaw periods. You need at least wait for a pullback within the trend in my opinion.
Backtesting this system is not recommended because the code references future data.
Excellent modification done for Kbrain. Now with this, chart shows clear trend.
Thanks for sharing
does this really look into future?
I can confirm that this does not look to the future.
Whipsaws can be avoided by using Linear regression channel with the system…I am trying to do that and pretty good results
