Personally I find $20,000 with standard AIM is the minimum I want to start with. $10,000 in stock which gives min trade of $500 and profit of $75 on first sale.
With LD AIM 5% SAFE, 10% MIN ORDER SIZE you might start with $3,000 in stock and $10,000 in cash ( or a bit less at bottom of market ). Your first trade will be $1,000 with a $100 profit if a sale.
Or don't use AIM and just buy or sell on a 20% move.
Or just buy a few things and rebalance once / year till the account grows.
No sense trading just to trade.
