docs: Set indicator to use (or not) integer positions for a given strategy or
          security.
  
          By default all positions in number of stocks should be integer.
          However this may lead to unexpected results when working with adjusted
          prices of stocks. Because of series of reverse splits of stocks, the
          adjusted prices back in time might be high. Thus rounding of desired
          amount of stocks to buy may lead to having 0, and thus ignoring this
          stock from backtesting.
