Detect cross of 2 lines accurately

I used the following code to detect crossover on conversion and base line, but it is not very accurate.

I need a way to detect crossover on conversion and base line very accurate. I tested on EURUSD daily chart from 2017-1-1 to 2018-1-1.

------------------------------------

   double t0, k0, t1, k1;

   t0=iIchimoku(NULL, 0, 9, 26, 52, MODE_TENKANSEN, 0); // Conversion Line

   k0=iIchimoku(NULL, 0, 9, 26, 52, MODE_KIJUNSEN, 0); // Base Line

   t1=iIchimoku(NULL, 0, 9, 26, 52, MODE_TENKANSEN, 1); // Conversion Line

   k1=iIchimoku(NULL, 0, 9, 26, 52, MODE_KIJUNSEN, 1); // Base Line

   // Conversion line cross above Base line(Close all Sell orders)

   if (t0 > k0 && t1 < k1){

CloseAllSellOrders();

   }

   // Conversion line cross below Base line(Close all Buy orders)

   if (t0 < k0 && t1 > k1){

      CloseAllBuyOrders();

   }
