Does filtering breakouts with ADX trend strength improve results?

We want to trade breakouts only when the market is actually trending, and skip breakouts that happen in a choppy, directionless tape. Enter long when the close makes a new 20 day high (the highest close of the prior 20 trading days) and the 14 period ADX is above 25 on the same bar. On the entry bar, measure the 14 period ATR and place a protective stop 2 ATR below the entry price. Size the position so that hitting that stop loses exactly 1 percent of account equity. Round down to a whole number of shares. Take profit at 3R, that is three times the distance between entry and stop, placed above the entry. If the 14 period ADX closes below 20 before either level is hit, exit at the next open (the trend has weakened). If the position has been held for 40 trading days without resolving, exit at the next open as well. Long only. One open position per ticker at a time. No leverage and no pyramiding.
