The basic principle of trading is that it is better to make a little profit than to lose a lot. Failing to gain greater profit was never considered a loss, while failing to obtain current profit was a loss for them. Prices can fall at any time for any reason, so they must be very wise in decision making and put aside greed in favor of greater profit.
For a trader, it is better to make a profit of $1k today before the price is corrected than to make a profit of $2k the next day but have to lose $2k first because of greed. They can buy the dip if they take $1k today, this can leave them with more capital than waiting for tomorrow.
that should be the basic but trading is so uncertain that you can't just set your target and everything will eventually come to place, sometime the market behave in strange way, i mean yes having small profit is definitely better than losing money but i'm sure many people that are experienced in trading knows that sometime the price bounce back after we are selling, due to haste decision we missed such a great opportunity of making money. i mean such thing might not be a good thing for future trading but certainly spot trading there are many occasion where the price bounce back even higher could give bigger profit if we were patient enough we can get that profit but taking that small profit just because market showing little sign of dumping we just missed that whole opportunity.
the concept of trading such as getting little profit is better than losing, buy high and sell low, is a good thing to follow but applying is so hard.
personally when it comes to trading see whatever fits our target, being flexible is the key that could help us getting profit in trading, if the market is showing correction but you're so sure that it will eventually come back, maybe its worth a try to take that little risk and see how things gonna turns out.
