Measured indicator guides
Forex indicator settings, tested
Each guide starts with how the indicator works, then tests its periods, levels or triggers on the same historical data. Profitable and losing settings stay in the tables so the result can be checked rather than trusted.
Moving averages
Crosses, ribbon structure, averaging methods and distance from price.
