Well I figured maybe I should get serious and start working on strategy backtesting. All the pro's do, don't they? Or are there still some pure discretionary traders out there? I have never placed much faith into systems partly because I only trust my own observations and feel computer generated systems hide too many factors. I also have little interest in programming not that I didn't try to read programming books (I would just give up after a few pages), and finally I traded mostly intraday. Recently I turned to swing trading (stock indices) in its true meaning and had good results. It seems the more I stay away from the puter the better I do. I want to keep working in this direction and trade mostly EOD. However if I want to give some credibility to my strategies and experiment new ones in currencies or commodities at some point I 'll have to backtest. I thought I could start with Excel. Does anyone know how to learn about the excel functions used to backtest? The other reason why I never really considered backtesting is the cost of softwares, it would not make sense to me to spend 10% of my capital per year on all kind of softwares . I know about TS, Metastock etc, these are just not an option. I also heard about Wealth Lab being very popular but it's sold for $650. I just need simple stuff, no indicators, just price action and MA's and I forgot to say decades of data on ND and SP, TY, GC and currencies. Please no need to reply if it's to tell me I have no business trading if I can't spend a few hundreds per month for software. Thanks.
