Having trouble with my profits showing negative

on my profits some show negative then other show positive or [no sign at all] now I don’t know if it was slippage or if I didn’t wait long enough to make sure of the trade! if this would cause the trade to be in the negative, now a few times I just deleted the trade realizing it was not a good time to take the trade. I have no idea .

Are you trading with real money? If so, I’d recommend stopping.
It sounds like you need to go over the fundamentals once more, and, demo trade on your brokerage platform to become more familiar with the interface.

Are you saying that as soon as you enter a trade, you’re seeing price move slightly in your direction, but your position remains negative?

Keep in mind, if you’re getting into a long position via a market order, you’re hitting the ask (or, offer).
To get out via market order, you’d need to hit the bid. The bid / ask spread is something critical to understand.

When you go long via market order, and all else is equal, your position will be negative because of the bid/ask spread.
