see how strong this pair is. If you short prematurely, then you would have to have a much higher SL and also tie up your available capital to take on other opportunities. This will foul your trading mood as you stare in the red each day you turn on the PC while waiting and hoping it reverse sooner than later.
Remember we are trend followers so follow the trend not decide the trend or dictate where it should go. It could go much higher than 1.334 before pulling back and if that happens and you are not willing to accept losses, you are likely to keeping stretching your SL wider and wider while seeing a higher drawdown. Been there, done that, does nothing for the ego nor the pocket. Burnt a few portfolios, made same mistakes several times due to greed, ignorance and over confidence.
When your funds are so low and you are so desperate to trade to make a comeback, that is when reality bites and make you really really be cautious. It does not matter if you make cents profits so long as you stick to your strategy of following the trend and not against it. Easier said than done and I believe only experience would truly make a trader learn his lessons.
Don't make the mistakes I made though I still receive same emails or PM about this. I can't share your financial losses but I know very well the emotions you go through.
Stay strong , stay in the game.
