These are few challenges faced when I newly got into trading, which I think I should share so people who are new traders should know.

[1].Don't Chase the market:
There is always a next opportunity in the market,
If you miss this opportunity wait for next one.

[2]. Always be patient with your trading set ups:
 Sometime it takes you up to a week or more for a trading set ups to get complete before executing a trade.
Secondly, sometimes it's good to wait for your stop lose and take profits to get triggered and don't close them yourself out of fear.

[3].Don't predict the market ,react to current market situation.
This is what that cost me blew a lot of my trading capital. Always wait for trend direction and follow the trend , As they say... trend is your friend until it's finished.

[4].Don't outsmart the market :
market does whatever thing it wants to do, so don't be too smart wait for confirmation.

[5]. Don't be greedy:The master of it all.
Greediness can reap you off all your profits already gained from the market when you're trying to gain it all. Be comtempted with the profit you've got and have plans for profits taking.
This is one the biggest challenge I faced during my early time of trading and even now but it's reduced and controled.
