exponential trend: EMA (1 * (indexc-LLV (indexl, 34))/(HHV (indexh, 34)-LLV (indexl, 34)), 3), color ffaa66, line thick 3;

boundary between strength and weakness: 8,COLORYELLOW;

concentration of main chips: winner (c) * 1, colored, line thick 2;

the concentration of chips raised in a random way: (winner (c * 1.1)-winner (c * .9)) * 1, color green, line thick 2;
