The only killer in the market is hesitancy to take a loss. The odds of a trade is positioned against us always and everytime. For example, you get in a position at 26000 mark and get out same at 26000, you will become poorer by some few hundreds because of the cost of the trade. We know that we need to get out of trade, if it moves against us. But somehow we donot like to close the trade when it moves against us. But by EOD, we kick ourselves for not closing the trade in predetermined stop. This is to be addressed first.
If you repeatedly fail to close the trade at SL, it is a serious problem. Whatever the justification you may give for holding a loosing trade, you are wrong.
Look at the trade position size, to assess the burden of loss in a loosing trade. If it is bigger than what you are prepared to loose, fix it immediately. Otherwise you are likely to be addicted to random rewards of the market and eventually you are likely to fail.
