How to trade using a set and forget method?

Here is method.

try it
feedback if possible please

basis
past day high and low
or
past 3 day high and low for advanced traders

method
here is mechanical set & forget entry exit levels for currencies.
The clue was
buy stop entry @50%level,target @20 pips above for long,stoploss @20 pips below entry
sell stop entry @24%,target @20 pips below,stoploss @20 pips above sell entry
this seems to work half the time or fail half the time with minimal loss. Result=safe trading practice.
Set & forget
it works in currency MT4 after long entry and target get done,stoploss gets cancelled automatically.

will post more soon.
