I am trying to calculate the 3 day slope of PPO-Histogram according to the SCTR short term indicators. Does tradestation's easy language has command to compute the slope? Now I can compute the PPO-Histogram of 3 days by the following codes. But don't know how to calculate the slope. I think the slope should be based on linear regression.

PPOValue0 = PPO(Close, 12, 26);
PPOAvg0 = XAverage( PPOValue0, 9 );
PPODay0 = PPOValue0 - PPOAvg0;

PPOValue1 = PPO(Close[1], 12, 26);
PPOAvg1 = XAverage( PPOValue1, 9 );
PPODay1 = PPOValue1 - PPOAvg1;

PPOValue2 = PPO(Close[2], 12, 26);
PPOAvg2 = XAverage( PPOValue2, 9 );
PPODay2 = PPOValue2 - PPOAvg2;

Thanks,
Raymond

a long time ago i was also interested in calculating the slope of some indicators but was never able to get ts to do that. in the end i decided to use percentage change, which is quite similar.


ts does include some trigonometric functions like sine, cosine and others and i think it can also calculate linear regressions, so maybe you can create some workarounds to approximate the values for slope with other functions.

Hopefully I understand your needs correctly, but here goes. The equation for slope is rise/run and we know run = 3 since that is what you are interested in. Rise is the same as delta value, so it should be (PPO[0]-PPO[3]) / 3.
