I'm new to easy language and I'm a bit confused about the syntax when comparing the value of the stochastic now versus one bar ago.

The stochastic is computed as follows:

ok = Stochastic(High, Low, Close, 14, 3, 3, 1, oFastK, oFastD, oSlowK, oSlowD);

And the "value" I am looking for is oSlowK - oSlowD. So this is the value at the current bar. How do I get the value at the previous bar? One possibility is this:

ok2 = Stochastic(High[1], Low[1], Close[1], 14, 3, 3, 1, oFastK1, oFastD1, oSlowK1, oSlowD1);
value1 = oSlowK1 - oSlowD1

But is it also (instead) possible to just use this:

value1 = oSlowK[1] = oSowD[1];

What is the correct syntax?

westofpluto 

ok2 = Stochastic(High[1], Low[1], Close[1], 14, 3, 3, 1, oFastK1, oFastD1, oSlowK1, oSlowD1); value1 = oSlowK1 - oSlowD1

westofpluto 

value1 = oSlowK[1] = oSowD[1];

I believe the two code snippets should provide exactly the same answer. As a test, put both sets of code in the same indicator and plot them. I would expect they would be the same line.

westofpluto,

you can reference previous bar's values for variables (just like you can do for some reserved words) using [x], where x is the number of bars back starting from the current bar, which is 0.
In your case both ways will work, but since you likely call the stochastic already within your code getting the previous bars values using oSlowK[1] and oSowD[1] will be more efficient.

If you haven't done so already, I would suggest checking out the free EasyLanguage Essentials PDF that you can download on the Tradestation website. It will bring you up to speed in terms of the basics of EasyLanguage.
