So to avoid more lose as a trader accept your losses and move on, keep an open mind and you will start gaining more than you are losing.
Life happens your loss should be used as a lesson and motivation to achieve success.
Before we even talk about losses this much, a trader who has a good knowledge about trading, and probably has studies a whole lot about trading need no body to tell them that losses are a norm with trading and accepting it is part of trading too. Somehow I think because some persons do not wait to be well grounded before hoping on the chart, you see them finding it difficult to accept loses and so they have a very terrible approach to it when they suffer it, they become aggressive and impulsive with their next set of trades.
This is why having a trading strategy is always very crucial and making sure to be disciplined enough to follow up with that strategy will be another saving grace. A typical situation whereby you have a good strategy and a good risk management system with a risky to reward ratio of about 3:1, I don't see a reason why you will panic so much when you get a loss, for this you know that you need to suffer three losses in a row before you become agitated and you also know that a single win
cncan make up for all of that so you need not take bigger lots or position or even a higher leverage to make up for loses. This is why it is essential to have a good knowledge to get on the chart so you don't suffer losses that messes up with your psychology and trade.
Define your risk, know your edge and always stick to your strategy/trading plan so loses don't feel like a big deal since you have it preplanned know how much you were willing to loose at a go.
