Function Prototype

/* Accumulation/Distribution Oscillator */
/* Type: indicator */
/* Input arrays: 4    Options: 2    Output arrays: 1 */
/* Inputs: high, low, close, volume */
/* Options: short period, long period */
/* Outputs: adosc */
int ti_adosc_start(TI_REAL const *options);
int ti_adosc(int size,
      TI_REAL const *const *inputs,
      TI_REAL const *options,
      TI_REAL *const *outputs);

Description

This documentation is still a work in progress. It has omissions, and it probably has errors too. If you see any issues, or have any general feedback, please get in touch.

The Accumulation/Distribution Oscillator is also known as the Chaikin Oscillator after its inventor.

It takes two parameters: a short period n and a long period m. The indicator calculated by taking a moving average of n periods of Accumulation/Distribution Line subtracted from a moving average of m periods of Accumulation/Distribution Line. The moving average used is Exponential Moving Average.

Example Usage

Calling From C

/* Example usage of Accumulation/Distribution Oscillator */
/* Assuming that 'high', 'low', 'close', and 'volume' are pre-loaded arrays of size 'in_size'. */
TI_REAL *inputs[] = {high, low, close, volume};
TI_REAL options[] = {2, 5}; /* short period, long period */
TI_REAL *outputs[1]; /* adosc */

/* Determine how large the output size is for our options. */
const int out_size = in_size - ti_adosc_start(options);

/* Allocate memory for output. */
outputs[0] = malloc(sizeof(TI_REAL) * out_size); assert(outputs[0] != 0); /* adosc */

/* Run the actual calculation. */
const int ret = ti_adosc(in_size, inputs, options, outputs);
assert(ret == TI_OKAY);

Calling From Lua (with Tulip Chart bindings)
