PnL price different from Chart price

[Hookway]

Hello

Re:attached

the prices on the chart differ from the price used to calculate the PnL

In the example in the image attached

the AUD price is 0.64652 for PnL purposes

but it is 0.64643 on the chart

Is one the real time price, and another delayed or is it the spread, there some other cause for the difference?

Please let me know

You buy at the ask and sell at the bid.  I cannot see if your positions are long or short.  Turn on the bid and ask lines on the chart (right click on the chart, select properties, click the "Show" tab, and turn on the ask line).  If you have a short position, to close it you must buy at the ask, so the ask price is the relevant price when calculating profit.  I suspect your spread (Ask - Bid) = 9 points (.64652 - 0.64643) at that moment in time when you captured the screen shot.

Thank you!  Got it, you're right its a 9 pip spread

Hookway #: !  Got it, you're right its a 9 pip spread

Wrong, it's 9 points. A PIP is not a point.

PIP, Point, or Tick size 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 (if any still exists), exotics (e.g. USDZAR where spread is over 500 points), and metals. Compute what a logical PIP is and use that, not points.
