  1. Perhaps you should read the manual. Timeseries and Indicators Access

  2. PIP, Point, or Tick are all different in general.

    Unless you manually adjust your SL/TP for each separate symbol, using Point means code breaks on 4 digit brokers, exotics (e.g. USDZAR where spread is over 500 points), and metals. Compute what a PIP is and use it, not points.

  3. Was this so hard you couldn't do it?

    double openPrice     = iOpen( _Symbol, _Period, 0),
       closePrice    = iClose(_Symbol, _Period, 1),
       difference    = openPrice - closePrice,
       pip           = _digits % 2 ? _Point : _Point * 10,
       pipDifference = difference / pip;
