well, you know the big bull move that GBP/JPY made that was 50,000+ pips? what about XAG/USD back in 2011? economic conditions change market sentiment too. that's why i have started focusing on building an EA that trades strictly off of price action and volume. it uses no indicators, and is not adjusted for fundamentals. based on my experience, by following the institutional money flow in the markets, i can get the most consistency out of trading. but just for extreme things like i first mentioned with the yen and silver, if you get caught in a bull market, you can buy anytime and make money.. in a sideways market, you need to know how to play a range, and in a bearish market, you will have a hard time finding the bottom.
as far as my system, right now it is only taking short positions since i have not coded the long position strategy into the EA yet. i'm curious to see how it'll perform with that, or with hedging both long and short positions simultaneously. maybe i will manually adjust the EA to take long positions only in bull markets, short positions in bear markets, and hedge both long and short in ranging markets.
