Trade small during times of uncertainty. 

Instead of are taking large trades in this time of uncertainty,  it is better to take smaller trades get feedback and trade again.

Taking too large a trade can bring big returns but when one is wrong too many times it could blow one's account and end up being out of the game. 

It is not about making the most amount of money in the shortest time especially when the market is uncertain, instead, being able to consistently take a overall profit until market conditions turns to be clearer then go for larger trades

A mistake I made a month ago on $Albemarle(ALB)$  is to try to buy the dip and buy increasingly large positions  and when the market keeps falling you run out of funds and get trapped. Instead if I have traded smaller, I would have made money even on a small recovery.
