I am nutting out a strategy by looking at charts manually and with a pen making notes. In the absense of a computer knowledge and programming know how what kind of sample size would be sufficient to ascertain if the strategy works before using more samples to validate it and then paper trade it?
200 different stocks?
100 different stocks but with multiple times focussed on?
10 stocks with their life history studied?
I am interested in the responses here from all who have dabbled in testing or manually tested with paper and pencil.
