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.

Qstick can be used to quantify the ratio of recent up-bars to down-bars.

Qstick takes one parameter, the period n.

It is calculated for each bar as follows:

Example Usage

Calling From C

/* Example usage of Qstick */
/* Assuming that 'open' and 'close' are pre-loaded arrays of size 'in_size'. */
TI_REAL *inputs[] = {open, close};
TI_REAL options[] = {5}; /* period */
TI_REAL *outputs[1]; /* qstick */

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

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

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

Calling From Lua (with Tulip Chart bindings)

-- Example usage of Qstick
qstick = ti.qstick(open, close, 5)
