Hybrid Convolution Filter

Introduction

Today i propose an hybrid filter that use a classical FIR architecture while using recursion. The proposed method aim to reduce the lag generated by fir filters. This particular filter is a sine weighted moving average , but you can change it since the indicator is built with the custom filter template (1). Even if it use recursion it still is a FIR filter since the impulse response is finite.

The Indicator


In red the hybrid swma and in blue the classic swma of both the same period. The difference can be seen.

The switch between the input price and the past values of the previous convolution values is made by using exponential averaging, the window function is the same as f(x) in the code.

Any filter can use this architecture, the indicator is built around the custom fir template, see (1)

Conclusion

I presented a FIR filter using recursion in its calculation, the integration is made with respect to the proposed template, therefore any user can simply modify f(x) to have different filter without the need to make any change. However curious users might want to change the window function of the exponential averager, in order to do so change sgn = f(i/length) in line 11 for sgn = fun(i/length) where fun is your custom function, make sure to add it at the start of the script where all the other functions declarations are.

Thanks for reading !

What a great enhanced improvment for the FIR filter; thank you Alex =D

Great, as usual! i would love to see what you come up with if you incorporate volume, for instance, VWAP is used by institutional investors and volume profile is a great way to see where institutions are accumulating, https://www.youtube.com/watch?v=AN1jpwCLOWo

@DannyBaker, sometimes following the market makers/institutions is the best thing we can do
