public int getPipsAverage(long time, int numPer) {
            try {
                IHistory history = context.getHistory();
                //
                long firstBarTime = history.getPreviousBarStart(mPeriod, time);                    
                List<IBar> bars   = history.getBars(instrument, mPeriod, OfferSide.BID, history.getTimeForNBarsBack(mPeriod, firstBarTime, numPer), firstBarTime);
                //
                int  diff  = 0;
                int  count = 0;
                for (IBar bar: bars) {                    
                    double high  = bar.getHigh();
                    double low   = bar.getLow();                        
                    int    range = (int)Math.round(numberOfPips(high,  low));
                    if (range > 0) {
                        diff  = diff + range;
                        count = count + 1;
                    }                    
                }
                return diff / count;        
                //

                logger.error(e.getMessage());
                return -1;
