The first practice I was at in the US was a 2 doctor office. I worked in one half with 2 assistants and the other dentist in the other half.

One of my assistants had been in the business for over 30 years. She knew her s**t. When my colleague relocated, I asked the

Quelques noms détaillés 👇

A) Open to Close abs %.
No. of trading days 2160
No. of days open to close > 1% = 750 (35%)
No. of days open to close > 2% = 247 (11.5%)
No. of days open to close > 3% = 58 (2.7%)
No. of days open to close > 4% = 13 (0.60%)
..
......
No. of days open to close > 5% = 4 (0.20%)
No. of days open to close > 6% = 2 (0.09%)
No. of days open to close > 7% = 0 (0%)
% is absolute of + / -, ie can be either up or down.
So essentially at the minimum one should ideally trade only 35% of the times intraday...

During 1% move, ie 750 times, 38% times (288 dys) CPR width was < 0.68 times 20 day average; Out of 288 dys, 89% (255 dys), PDR was < 2%.
During 2% move, ie 247 times, 37% times (92 dys) CPR width was < 0.68 times 20 day average.
