OSCP function - What does this do?

AFL Programming
#1

r1 = Param( "Fast avg", 9, 2, 200, 1 );
r2 = Param( "Slow avg", 18, 2, 200, 1 );
Plot( OSCP( r1,r2), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );

Hello, can anyone tell me what r1,r2 means int he above code? Is it divide r1 by r2? what is the outomce of r1,r2 please?

See the manual for OSCP http://www.amibroker.com/f?oscp
r1 and r2 are parameters for Price oscillator. All "oscillators" are generally differences. In this case it is difference between two exponential moving averages (similar to MACD line)
