Hi Donkers - Marc Rivalland's book is an excellent manual for swing trading, and I can't think its necessary for a swing trader to have more in formation / tactics at his disposal. That said, I find one of the frustrations inherent in Rivalland swing trading is the number of days that must separate swings. I mean that in a trend you need a swing in the opposite direction to allow you an entry point, and the swing must be at least 3 days long. This is a personal issue and it doesn't make Marc's method any the less practical.
I definitely cannot recommend Alan Farley's Master Swing Trader. The best I can say is that it is 'scholarly', and that's also the worst I can say about it.
Strategically though, money management discipline is absolutely vital to keep you in the game and isn't addressed in Rivalland. See books by Alex Elder.
I find I only need to trade one index, the FTSE100, but as it basically follows the S&P I refer to the S&P whenever chart patterns might be ambiguous on the FTSE. Tracking multiple markets is stressful and time-consuming so I either trade the FTSE or rarely metals but not both simultaneously. There are two nice things about the FTSE - it tracks the US markets, so we can often see by mid-evening here what we will do tomorrow, as New York is closing at that time by the UK clocks. Secondly, the index features real gaps between close and subsequent open - so does the S&P and the Nas I think but many markets, like the Dow, are not permitted to 'gap', while others like FX I think are 24hr markets so real gaps can not occur. Gaps are not essential for swing trading, but they tell you something about market when they occur.
