Currency Strength Indicator with MTF and coefficient considerations

Hello developers,

I would like to have a Currency Strength Indicator based on the exact same principle as this indicator : https://www.mql5.com/en/market/product/11131#

I need to have the choice between 2 different displays : the classic one (identical to the one of the above indicator) and a Multi-Timeframe display.

The Multi-Timeframe display needs to show curves corresponding to the averaging of several chosen Timeframes. In addition I would like :

1) the possibility for the calculations, to apply a desired coefficient to the value of a chosen Timeframe (those values change in real time for the current candle because they are related to closed candles)

2) possibility to draw horizontal lines (on the same subwindow as the indicator) corresponding to the averaged values of each currency. Those lines don't change in real time because they have to correspond only to the last closed candle of each timeframe (last "fixed" values).

3) I wish a kind of alert to inform if all the calculations about the 28 pairs are correctly done, or if data is missing (in order to work with correct curves and values only).

4) I also need the possibility to choose a specific period number for each Timeframe separately.

Further explanations will be given but for now I assume this project is clear enough.

Regards

Richard
