Help with coding of Indicator based on GAPS as Support & Resistance


Hello Guys how are you?

 Well i'm doing fine, but stuck with an idea i have for an indicator i'm creating, there are some rules i developed and right now trading a strategy based out of this manually, but i think my trading would be more effective if i had the indicator i am trying to create, but stuck as i have low training in coding...

 Well what i had was another indicator i created with some help for breacking support and resistance in multitimeframes drawing arrows, it was not a big long extended indicator it ws simple so i took it and started looking how could i make it work into this new idea, so i will need a hand to code for me or make simple changes....


 For that i think the code for showing them as simple lines that last 60 min or a sepcified time would be something like:

double Buy[],

int OnInit() {

   for(int i=0; i<4; i++) {
      SetIndexStyle (i,DRAW_ARROW,STYLE_SOLID,2);} //how to make it draw a line instead of arrows???
   SetIndexArrow (0,233);
   SetIndexArrow (1,234);
   SetIndexArrow (2,233);
   SetIndexArrow (3,234);

void OnDeinit(const int reason) {}

int OnCalculate(const int rates_total,    const int prev_calculated,    const datetime &time[],
                const double &open[],     const double &high[],         const double &low[],
                const double &close[],    const long &tick_volume[],    const long &volume[],
                const int &spread[]) {
   static int lastSignal=0;
   for(int i=MathMin(rates_total-prev_calculated, rates_total-2); i>=0; i--) {
      if((Open[i]-Close[i+1])>0) {
      Buy[i]=Close[i+1]; } //How to draw a line blue color at this price of previous candle close that last only 60min?
      Sell[i]=Close[i+1]; } //How todraw a line red color at this price of previous candle close that last only 60min?

 So this is the first part of the code i need somebody help me make the fixes for 1: instead of drawing an arrow, to draw a line, below current price blue and above current price color red,and that the lines last 60min or the time the user like to use...

 I hope somebody can help, thanks
