Conditions 1 and 2

The Entry formula displays a marker on the chart if the price bar matches the conditions of the formula. The Exit formula results in a marker.

When you select the checkbox in the {1and2toolbar} every price bar matching your formula is marked. If you deselect the checkbox you'll only see a when there's already been a - you will never see two or more or in a row.

e.g. If you use

     close > open

as your entry formula and

     close < open

as the exit, when the checkbox is ticked you'll see a huge number of and markers. However, if you untick the box you'll notice fewer markers, and they'd switch between and

Conditions 3 and 4

If you're using the alternate pair of 3/4 indicators then the markers will be and instead. They can also be chained (displayed one, then the other) or set to display every match.

Advance/Decline Ratio

Advance includes all stocks which closed higher than the previous price bar. Decline is the opposite - all those stocks which closed lower.

Calculates all the advancing and declining stocks for the given range of dates. The ratio is based on the price data in your database, which means any incorrect or missing data will lead to incorrect results.

Therefore you should use the Advance/Decline ratio in FCharts as a quick guide, and not rely on it for absolutely 100% accuracy.
