  1. The forming candle is index zero. The Oldest candle is index Bars-1. You are trying to read the future.

  2. You used NormalizeDouble, It's use is usually wrong, as it is in your case.

    1. Floating point has an infinite number of decimals, it's you were not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)

    2. Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.

    3. SL/TP (stops) need to be normalized to tick size (not Point) — code fails on non-currencies.

      And abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum (2012)

    4. Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on non-currencies. So do it right.

    5. Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.

    6. MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

    7. Prices you get from the terminal are already correct (normalized).

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

    Thanks for your reply.

    I was trying to tweak the shifts to get the value of different candles, if you notice I've also shifted the entire MA, so the candle then I was getting value is from previous day and not future.

    Also, when doing position sizing calculator, the decimals need to be limited to result in a proper calculation outcome. Do you know a way to do that without using Normalize Double or DoubletoString, or any other method that does not change the result?

    Integers don't have this "problem". You could multiply the double values such (divide by _Point value) that you get rid of the fraction, then cast the double to an int (long) and do the calculations. When done, you divide (multiply by _Point) again to get your original double fraction part back.

    This way you eliminate the drift introduced by floating points.
