Function Prototype

/* Median Price */
/* Type: overlay */
/* Input arrays: 2    Options: 0    Output arrays: 1 */
/* Inputs: high, low */
/* Options: none */
/* Outputs: medprice */
int ti_medprice_start(TI_REAL const *options);
int ti_medprice(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 median price indicator calculates the mean of the high and low for a bar. Despite the name, it does not calculate an actual median value.

$$medprice_{t} = \frac{high_{t}+low_{t}}{2}$$

Example Usage

Calling From C

/* Example usage of Median Price */
/* Assuming that 'high' and 'low' are pre-loaded arrays of size 'in_size'. */
TI_REAL *inputs[] = {high, low};
TI_REAL options[] = {}; /* No options */
TI_REAL *outputs[1]; /* medprice */

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

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

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

Calling From Lua (with Tulip Chart bindings)

-- Example usage of Median Price
medprice = ti.medprice(high, low)
