Another way to think about it is this: the moment your entry order is filled, you start out in the hole / down 4 pips, at that very moment. That figure (negative spread value, here -4 pips) remains part of your Unrealized P&L throughout the duration of the trade. When your exit order is filled, that figure becomes part of your now Realized P&L for the just closed trade.
That perspective might help you become more keenly aware of the true R/R ratio of short-term / short-distance trades, much worse than the apparent R/R rario at first glance (when the hurdle to overcome is a 4-pip spread). "Worse," as in -- much higher % win rate needed to break even or better.
TP ... SL ... apparent R/R ... true R/R ... true / apparent
6 ....... 6 ....... 1:1 ....... 5:1 ........ 5
6 ..... 14 ..... 0.43:1 ..... 1:1 ..... 2.33
14 ..... 10 ..... 1.4:1 ..... 3:1 ..... 2.14
24 ..... 32 ..... 0.75:1 ..... 1:1 ..... 1.33
100 ..... 50 ..... 2:1 ..... 2.26:1 ..... 1.13
Note the trend in the last column as your TP and SL increase.
