How to calculate cost of keeping a position overnight

Postby arjfca » 21 Aug 2012

Hello

I never kept a position pass the cut off hour. Mainly to save the interest cost to carry on a trade overnight. I start to think that it me be profitable to kept it sometime even if it cost me some $.

Dummy question: How do I evaluate the cost to keep Eur.Usd overnight

Any input appreciated

Hello Martin,

Could you explain, what exactly you would like to calculate in MC? Do you mean that you want your strategy to take into account the sum of money charged by your broker for maintaining overnigh position?

Hello Andrew

I want to adjust my position size by including or not the rollover cost estimate. My size is calculating by the risk + my cost + slippage ( estimate) + fee (interest charged) to keep position for 1 day

All i'm looking for is a basic formula. No need to get the exact value

By knowing in advance, I could evaluate the pertinence of exit and or keeping the position .

1. What is the "risk" in this partisular case?
2. What cost do you mean? Cost for maintaining position overnight?
3. What is fee (interest charged)? Is it different from cost?

Hello Andrew

I think i have resolve my question

Here is my calculation:

Risk$: amount of $ per transactions. ( 50$)
Quantity of unit = $ risk / Pip at risk + slippage

$ risk = Amount per transaction - Transact fee ( 5$ per 100K) - cost to keep over night

I will use 5% as interest charge

Calculation to be:
$ risk / pip at risk + slippage = InitQuantity

InitQuantity * Entryprice + slippage (2 pip) = Amount borrowed to broker

Amount Borrow to broker * 5% / 360 = rollover$

New quantity = $ risk per transaction - Rollover$ - Transaction fee / Pip at risk + slippage

This is not exact, but I don't need to. Also, I understand that I may get paid interest depending on the pair traded and if the initial transaction is Long or Short. I just want to make sure that if I risk 50$ per transaction, I don't risk 60$ when I add all the other cost.
