Any broker with variable Commission(e.g. $3 -> $0.3) mini-lots?

Hello Folks,

due to my trading approach I would need a broker with commission and due to that low spreads.

Or easier say: I need 1.0 pip spread on GBP/USD, max 1.2 pips.

My question: Is there any broker with a variable Commission which goes down to minilots?

Example Broker where that is possible:
Oanda:
1 Lot per side costs $5
0.1 Lot per side costs $0.50

That's what I need. My problem is: I cannot start with 1 Lot because I need sometimes 10 times higher than my initial position (so that would be 10 lots or even more, that is too crazy).

I give you an example what does not work:
Let say robomarkets:
1 Lot per side costs $1
0.1 Lot per side still costs $1

So If I trade only 0.1 Lot I pay 1 pips spread only for commission + their spread so I'm at 1.6 pips again and that is too much.

Any other broker out there like Oanda with a variable commission under 1 lot?

Thanks in advance

Edit: Problem with Oanda is the spread is still too high. Example: GBP/USD: Spread: 0.5 pips + 1 pip commission = 1.5 pips (the commission of 1 pip is 2x$5 for example). I need 1 pip spread on GBP/USD.

I'm pretty sure that the commission is always variable. If a certain broker has a commission of let's say 10 units of currency per Lot, for 0.50 lots it's going to be 5 units, for 0.10 lots it's going to be 1 unit.
Are you sure you got that right? I've traded with dozens of brokers and I've never encountered it. Just doesn't make sense to me.

As for this, I can give you a recommendation. You can check out my main broker, FXOpen.
Here's the breakdown of GBPUSD costs for their ECN account type:
The average GBPUSD spread is about 0.3 pips
The round-turn commission is 5 units of base currency per lot. So, for GBPXXX pairs it's 5 * 1.22 (current GBPUSD rate) = 6.1 USD per lot, which is approximately 0.6 pips.
So, the total costs are 0.3 + 0.6 = 0.9 pips.
But I also get a rebate through a rebate service, which is about $2 per lot at this time.
So my total costs are about 0.7 pips.

Here are some of my GBPUSD trades from this past week. As you can see, the commission is variable.
FXOpen ECN, the account currency is USD

Awesome, thanks a lot! I have to check that out. I was always wondering how quite a lot people could trade like that because smallest position would be 1 Lot. Now it makes sense, if you are able to trade 0.1 Lot or even 0.01 Lot (1000 Units) and the commission adapts accordingly, than it is a complete different picture.

To understand you correctly:

100.000 Units costs you let's say 6.1 USD
10.000 Units costs you accordingly 0.61 USD
1.000 Units costs you accordingly 0.06 USD (if offered)

I assume some brokers say: Minimum 0.1 Lot size for ECN trading. I know on Metatrader minimum lotsize is 0.01 Lot (1000 units). I think it was tickmill broker who allowed to trade only 0.01 lot and accordingly only 0.05 USD comission (so you still are at same conditions as trading 1 lot).

That sounds awesome. Much better conditions as now.

Correct.
Yes. Overall the conditions have been improving, and microlots have been a common occurrence with Metatrader brokers for quite some time. I've been trading with FxOpen for more than 10 years, and they introduced the minimum 0.01 lot (1000 units) on the ECN account in 2015, if I remember correctly. Previously, it was 0.10 Lot. And some other brokers introduced it even earlier.

By the way, the commissions may vary according to the account balance and/or traded volume.
For example:

Account balance Commission (round-turn)
below $1000 = 7 units of currency per Lot
above $1000 = 5 units of currency per Lot
above $25K = 3.6 units of currency per Lot
above $250K = 3 units of currency per Lot
