Hi,
here is ACD system applied on 10-min opening range on NF.
(applied on todays trading)
Setup:
-------
Candle size is choosen as 2.5 min, so first 4 candle will make opening range. Here OR cames 2704-2688 (16 points). In deciding the A( or C) value these should be kept in mind:
a) Running daily ATR(10 period) on previous days, its approx 100-110 points since last 2-3 days. This value is "theaoritical possible" range of a day ( high-low). Because of day trade, if 10-min OR ( here 16 points) consume too much value from daily ATR ( say more than 25-30% of daily ATR) than trade generated may not be so efficient/profitable. After all trade signal will be valid beyound OR+(A or C value) for long and OR-(A or C value) for short.
Total OR+-(A or C) value should not run away of 40% of daily ATR and a day should be totally avoided if it runs away 60-70%.
b)"10-min bar ATR(10 bar)" on NF roughly ranges as
10-14 points as normal
16-20 points as extreme.
Given the nature of volatility of NF , whole "10-min bar ATR" value should be chosen as A or C value ( contrary to fraction as in Weekly Setup). So for sake of simplicity A or C values are 10 ponits here comes
2678( 2688-10) and 2714(2704+10).
c) once NF moves beyond these limits, trade exacution validity comes only if it continuously traded belyoud that limit for half time of OR -- here 5-min ( 2 complete candle of 2.5 min)
Exacution:
----------
After validation , trade can be exacuted in conjunction to other indicator.
Here ROC is used.
Errata : Above SL in figure is actully high of OR i.e. 2704, it has mistakely drawn to 2714 by me. please correct.
