Some stocks are erroneously rounding their non-latest days' prices to two decimal places.
Some stocks like KRN.TO and WRX.TO have their non-latest days' data rounding to two decimal places (even though it always shows four digits after the decimal point).
For stocks with small share prices, this error can be significant and should be fixed.
Edit:
It should be noted that these stocks are tradable at half-penny increments (so three digits after the decimal place where the first two digits after the decimal can be any digit, but the third one after the decimal place can be either a 0 or 5).
