You don't want to get a loss if you're closing the day with your positions and it doesn't matter whether you've gained much or just a little.
I think the fear of closing a lossing market dreads the trader but no choice on that. It is better to close a lossing market while it is still small than when the loss has accumulated. There is a way that you can manage a lossing market over the day. To that you can use the stop loss so that it stop the trade when it gets there.
