I am primarily a platinum trader
As you can see from this site: Action-reaction is used infrequently nowadays
Which is a shame because it still clearly applies to price action
And now we have better software
So am starting to backtest pitchforks on the momentum indicators
As you see here- pitchforks would have kept you in on the uptrend
Combined with volume and divergence they would also have got you out before the downtrend
TRADE AT YOUR OWN RISK
