We normally trade just one or two symbols per day, making several round-trip trades each day. When trading ETFs, each transaction is typically for 25% of the value of the portfolio, so we may use several trades to get in and several trades to get out of a position and complete a trade. Often, we use simple option calls or puts, and will use 5% or 10% increments of capital to trade those, typically not exceeding 30% of capital in an option.
 
This number of trades is typical for day trading, where the strategy is to capture very small gains on each trade, which is not too difficult, and compound those gains.
 
We use stop loss amounts that are different for each security we trade..
