Positive expectancy is not an edge, it is a historical expectancy of the same forex casino game i.e . This positive expectancy or so called edge of yours will fail in the future. This is why writing all sorts of analysis, without using it works, because it is never used for real trading.
Actually, it is. If you don't agree, please offer your own definition of an edge. By the way, it seems that the guy in the video uses the same definition of an edge as I do.
There are no forex systems with an edge. An edge is something that happens more often repeatedly, in a random situation or random forex game or a casino game.
This is a rather poor definition.
correction: Quite a few brokers pretend to give zero spreads . Of course, they charge commission for trading and slippages.
commission for trading and slippages = equals spread, so same thing .
Have you ever tried trading news with spreads vs. no spreads (but with commission)? It makes a world of difference even if that commission is quite large. As for slippage, it is a non-issue as long as the trade volumes are low.
