If I understand your question, you are referring to the spread as a cost which must be recouped before your trade can show a net profit, and you are asking what that cost is – in dollar terms – for various size positions.
One pip is worth 0.10 USD per micro-lot (1,000 units), or 1 USD per mini-lot (10,000 units), or 10 USD per standard lot (100,000 units).
I will assume the spread is 0.6 pips, as you stated in your post.
• If your account currency is USD, then we can calculate the dollar-cost you are asking for, as follows:
dollar-cost per micro-lot = 0.10 USD/pip x 0.6 pip = 0.06 USD
dollar-cost per mini-lot = 1 USD/pip x 0.6 pip = 0.60 USD
dollar-cost per standard lot = 10 USD/pip x 0.6 pip = 6 USD
• If your account currency is not USD, then the pip-values we used above will have to be converted into your account currency. So, for example, if your account currency is AUD, then we get pip-values in AUD by dividing the USD pip-values by the current price of AUD/USD.
Let’s say the current price of AUD/USD is 0.70836
Then, one pip is worth 0.10 USD / 0.70836 = 0.14117 AUD per micro-lot, or 1.4117 AUD per mini-lot,
or 14.117 AUD per standard lot.
These results can be calculated using the PIP VALUE CALCULATOR, as well.
Finally, as we did above, we multiply these AUD pip-values by the spread (0.6 pips) and get:
- dollar-cost = 0.0847 AUD per micro-lot = 0.847 AUD per mini-lot = 8.47 AUD per standard lot.
