Absolute Price Oscillator

Function Prototype

/* Absolute Price Oscillator */
/* Type: indicator */
/* Input arrays: 1    Options: 2    Output arrays: 1 */
/* Inputs: real */
/* Options: short period, long period */
/* Outputs: apo */
int ti_apo_start(TI_REAL const *options);
int ti_apo(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.

Absolute Price Oscillator helps follow trends and has several uses.

It takes two parameters: a short period n and a long period m.

Absolute Price Oscillator is calculated as follows.

Example Usage

Calling From C

/* Example usage of Absolute Price Oscillator */
/* Assuming that 'input' is a pre-loaded array of size 'in_size'. */
TI_REAL *inputs[] = {input};
TI_REAL options[] = {2, 5}; /* short period, long period */
TI_REAL *outputs[1]; /* apo */

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

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

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

Calling From Lua (with Tulip Chart bindings)

-- Example usage of Absolute Price Oscillator
apo = ti.apo(input, 2, 5)

Example Calculation

short period = 2, long period = 5
