Definition:

Koncorde is a mix of SIX indicators, 4 trend indicators and 2 volume indicators. Its representation is based on colored areas and not on simple lines, which (I believe) is also a certain novelty in the design of stock market indicators. The brown area and the red mean are trend and the green and blue areas are volume. For the calculation of the brown area (trend) an adjusted version of VIGIA is used, which is a weighted and amplified indicator composed of RSI, MFI, Bollinguer Bands and Stochastic. The green area and the blue area are obtained from the percentage change of the IVP (Positive Volume Index) and IVN (Negative Volume Index) indicators. Anyone reading the available documentation on these two little mathematical gems will discover that they ATTRIBUTE the volumes traded to either strong hands (IVN) or weak hands (IVP). In the case of Koncorde the strong hands are represented by the movements of the blue area and the weak hands by that of the green.
