Great insight! Love the input and I'm certain a lot of new traders can learn volumes from you, me as well. I backtest my ideas but typically only a few weeks to a month back for valid reasons. Mainly because unlike traditional strategies, I do not use a strategy tester therefore I do not have the luxury to backtest years of data in an instant at the click of a button. Each day I backtest, I have a full Microsoft Excel spreadsheet devoted to. So as you can imagine, it takes quite a lot longer to take the data from my broker, put it into excel, review the stats, save, then repeat for each day I backtest. On the bright side each night I am building up my database of spreadsheets for the pairs I collect data for I still have all my spreadsheets from when I first starting using excel... From my first excel system, system 3 , all the way up to my current, system 13. Fortunately I have backups in case my computer crashed, but I have filled up my jump drive to the max (1 gb of excel spreadsheets) I probably had around 2 gbs now, but no worries. The endless tweaking of the system has since died down to only once or twice a month now it seems, the goal is never to have to update it or change it, that's the dream... As time between updates continues to lengthen, I'm happy to say I'm getting closer and closer! Will see in the next year xD.
