Change From Top %
It shows the percentage change of the candle's decline from the candle's high during the selected time interval.
In order to use the change from top indicator, a period and time interval (number of candles) must be selected. In this way, the percentage difference between the highest price value of the pair in the relevant time period and the corresponding value in the selected bar is calculated.
When used as a variable when creating a strategy, it can be used as a confirmation rule in addition to indicator-based crossovers. In this way, it is possible to confirm whether there is an unusual movement in the candle at the time of the crossover, or to calculate the size of the change during the movement.
It may not always be the right approach to create a strategy based on the rules created with this indicator alone. In general, this indicator can be used for confirmation purposes. An example of such a confirmation is the use of the indicator to limit the decline of the price from a top when a short position is to be opened in the strategy.
To explain the use of the indicator, in the screenshot above, we have marked Breakout 1 and Breakout 2 on a strategy created for the points where the price crosses the moving average to the down.
The indicator will be used here as an additional check on the dates of the breakouts to limit the maximum point at which the price will fall too far. At the point of the first breakout, the price change with the top is -0.83%.
Looking at the second breakout, the % difference from the top was -1.64%.
In this case, by defining the change from the top indicator between -0.5% and -1.5%, short positions can be prevented from opening from the moments when the decline reaches saturation. In this way, fake positions that may close at a loss can be prevented.
The above set of rules will be sufficient to make the mentioned setup.

When designing an Algorithmic Trading strategy, multiple indicators are usually linked together to form a set of rules.
