Buy the ASK Sell the BID


Here are some helpful visitor comments received in the last 24 hours.

The first relates to the confusion regarding bid and ask prices experienced by beginner traders.

"This is the line I used to use when I first started."

"Buy the ASK , Sell the BID"

The second is an observation regarding trading systems offered by others and backtesting.

Posted by Dropout

Anyone offering a new system should be able–at minimum–to say that
they've manually backtested it for at least a year's worth of data,
resulting in "x" number of winning trades and "y" losing trades, for a
profit of "z."

However,
99.9% of the time, experts selling systems, and those posting their
systems on message boards, say, basically, "Here's a system I've been
fooling around with. I looked back at a few trades I could have made
with it, and it looks really good." Then, they and others who follow
their advice start trading the system with live accounts.

As you can probably tell from my tone, I think this is a bad idea.

Environment: Strong trending markets that make new highs that then proceed to fail by taking out a recent low and then reverse again to make new highs

Strategy Rules:

Long Trade

1. Look for a currency pair that is making a 20-day high
2. Look for a pair to reverse over the next 3 days to make a 2-day low
3. Buy the pair if it takes out the 20-day high within 3 days of making the 2-day low
4. Place the initial stop a few pips below the original 2-day low that was identified in step 2
5. Protect any profits with a trailing stop or take profit by double the amount risked
