Stock Market Order Types (Market Order, Limit Order, Stop Loss, Stop Limit)
Market Order
Most basic type. "I want to buy/sell now"
Be careful with stocks with rapid price change as the time from buy to actual purchase could be a few seconds
Limit Order
"I want to buy this stock, but I only want to pay this much"
Stop Loss
"wait for stock to rise to threshold price"
Good for an unsure stock, waiting for stock to start trending up
Stop Limit
Combination
"wait for stock to trend upwards then buy. with a set threshold"
