bug?

[Forex Trader]

Hello

I've faced something that seems to me as a bug. Reading supplied help with MT 4.0.225 I've tried to apply iAlligator function as described.

double jaw_val=iAlligator(NULL, 0, 13, 8, 8, 5, 5, 3, MODE_SMMA, PRICE_MEDIAN, MODE_GATORJAW, 1);

Result is visible on attached picture. For me this is not correct result

I'll appreciate any comments from MT guys.

Here's the result chart: Solid lines are from build-in alligator's indicator. Dashed lines are made by the script quoted bellow
