It is my understanding that most Stoch RSI indicators can add K period and slow period... is that something Sierra can deliver in its StochRSI?

If it helps, find below the MT4 code:


#property indicator_separate_window
#property indicator_levelcolor PaleTurquoise
#property indicator_buffers 1
#property indicator_color1 Lime
#property indicator_width1 2
#property indicator_level1 20.0
#property indicator_level2 80.0

extern int RSIPeriod = 8;
extern int PeriodK = 8;
extern int SlowPeriod = 3;
double gda_88[];
double g_ibuf_92[];
double gda_96[];
bool gi_100 = FALSE;
string gs_104;

int init() {
IndicatorBuffers(1);
SetIndexStyle(0, DRAW_LINE, STYLE_SOLID, 2);
SetIndexBuffer(0, g_ibuf_92);
SetIndexDrawBegin(0, RSIPeriod);
gs_104 = "MT4-StochasticRSI-Oscillator-" + "v1.1" + " (" + RSIPeriod + "," + PeriodK + "," + SlowPeriod + ")";
