Quote from JSSPMK:
Why do you keep beating the old drum about 1 trade, when OP's question refers to a line of events? Not a trade, but trading?
I'm not saying one can't have an edge.
If you made one trade today, you were trading.
If you made twenty trades today, you were trading.
But, one or twenty doesn't matter.
Each trade is an individual event and can go either direction.
Trade #1 is independent of trade #2. Trade #3 is independent of trade #2, etc. That's what a trader must understand and accept.
This is why many consider trading as gambling. Because the outcome of each independent trade is uncertain; hence, a gamble. If the outcome was certain to bring a profit, it wouldn't be a gamble.
