Having trouble with Support Vector Machine indicator

[brw32]

Hello,

I recently downloaded a SVM indicator from https://www.mql5.com/en/code/1437 along with the required library but I am having problems with the indicator updating while the chart is live. Unfortunately, the developer has not been active for quite a few years so I am hoping someone here is able to help. Currently, the indicator plots the data points used for training correctly upon attaching the indicator to the chart as seen here:

The SVM is trained and returns the back-test accuracy. However, the indicator never signals a new trade regardless of how long you wait as seen here (the red vertical line is the time where I attached the indicator):

If I switch time frames or manually refresh the chart the indicator will train a brand new SVM and plot the new data points but again new trades are never signaled:

The code contains the plotting of arrows for the initial data points here

for(int i=0;i<ArraySize(buys);i++)
        {
         if(buys[ArraySize(buys)-i-1])    BuyBuffer[i]=open[rates_total-i-1];
         else                             BuyBuffer[i]=0;
        }
      for(int i=0;i<ArraySize(sells);i++)
        {
         if(sells[ArraySize(sells)-i-1])  SellBuffer[i]=open[rates_total-i-1];
         else                             SellBuffer[i]=0;
        }

and is followed by the by the code for the new signals

if(rates_total!=prev_calculated && prev_calculated>0)
     {
      for(int i=(rates_total-prev_calculated-1);i>0;i--)
        {
         if(classify(handleB,i))    BuyBuffer[i]=open[rates_total-i-1];
         else                       BuyBuffer[i]=0;
         if(classify(handleS,i))    SellBuffer[i]=open[rates_total-i-1];
         else                       SellBuffer[i]=0;
        }
     }

 I have just made the switch to MT5 and don't really understand the code yet so I was hoping someone is able to offer some advice. Thanks!
