Prices are governed by the principal of Demand Vs Supply at IGX platform. MCP Is the price arrived at after considering all valid purchase and sale bids.
All Purchase & Sale bids are aggregated to trace a demand supply curve.
An example for calculation of Market Clearing Price (MCP) & Market Clearing Volume (MCV) is given below.

In the graph shown above:
a) Demand curve is drawn by plotting the sum of purchase (buying) data (volume) against price. This step curve has a slope downwards.
b) Supply curve is drawn by plotting the sum of sale data (Volume) against price. This step curve has a slope upwards.
c) These two curves intersect at a point. This is the point of equilibrium. At this point price for both buying and selling is same.
d) If a perpendicular is drawn from point of equilibrium to price axis i.e. Y axis it will meet at a point on Y axis. Price representing this point is market clearing price (MCP)
e) If a perpendicular is drawn from point of equilibrium to volume axis i.e. X axis it will meet at a point on X axis. Volume up to this point represents Market clearing volume.
f) All sale bides having price less than or equal to MCP value and all purchase bids having more than or equal to MCP value will be cleared for trade.
