the first trade you mentioned is correct.
for the second crossover, as you mentioned, the 30min stoch was still bullish.
so we would miss the downfall.
but if your risk appetite is large, you could have gone for the trade, considering that the fast stoch in 30min had started curving downwards and would cross below soon.
As I said earlier, this system is not for huge profits. It just provides decent points every day and ensures that you stay in the green at the end of each day.
Keep your expectations around 30-50 points each day, no matter what the day's range may be.
If we want to play safe, we should be ready to sacrifice some big swings as well, keeping in mind that small consistent returns are essential in the long run.
