I am sure that is true. However, the high frequency traders have been quite successful with the opposite approach:
risking very little, and staying in the market for seconds. Of course, they place 1000+ trades per day. Big difference in styles.
Styles are quite the opposite, I only check open positions one hour before end of session on last trading day of week, do get a printout of new trades on Sunday at noon. I had developed HFT for Crude Oil, and although if filtered low enough, it could do 1000+ trades a day, but the more trades the smaller profit targets, so I have reset mine for larger targets and happy with less trades.
