Re: RSI, I was always partial to IBD. When I compared IBD rsi to others, IBD for some reason was spot on.This was important for me as to when to sell or hold.
The formula is simple: You need the following variables:
The average of price change in percentiles for the last..:
3 month period (A%)
6 month period (B%)
9 month period (C%)
12 month period (D%)
Then you need to put two times more weight for the A variable.
Formula:
40 * A% + 20 * B% + 20 * C% + 20 * D% - 100% = the basis of rank calculation for the relative strength of the stock.
And then you need a tool to rank al the results from the stock universe against each other and give the best performance a 100% reading and the worst a 0% reading. All this can be done in microsoft excel...
