Hello Grahal, Peter,

Thank you for taking the time to answer me.

To be factual, here are my fees with each broker :

IG : there is no spread costs, instead there is a fee :

• for US stock : 2cents / action with a minimum of 15$, ( my mistake : 25$ is when you place the order by phone, I don’t know who does this anymore …)
• for Euro stock : 0.05% with a minimum of 5$

IB :

. for US stock : 0.005$ / share with a minimum of 2$ -1$ rebate because I place the order with prorealtime = 1$ :

. for Euro stock : 0.06% with a minimum of 3$ -1$ rebate because I place the order with prorealtime. = 2$

Conclusion

FOR US STOCK : IB IS THE CHEAPEST (1 to 5$ instead of 15$ for IG), for a trade value from 1000$ to 100 000$

FOR EURO STOCK : IB or IG are quite the same 0.05% or 0.06% of the trade value

The good thing with IB is the 0.005$ per share , so if I trade only 200 shares at 100$, the fee is only 1$ !!, or for  1000 shares at 100$, the fees are  5$, or 15$ with IG !

With a fee per share, It means also It is better to select a stock with a higher value rather than trading penny stocks.

FYI : I did not do a “sponsor” contract but two IG and IB independant contracts, I did not know it was feasible.

In fact when I called few months ago PRT to do autotrading with Interactive brokers, it is also  what they told : it should be done for this year, let’s wait….

Finally I had to do an excel sheet to  compare all fees because they depends either on the total value of the trade or on the quantity of shares.

To be honest, to answer  your questions, I focused more on the fees of IB and IG, which I never really did before, and it is quite interesting.

Conclusion :

I will do autotrading with IG on euros stock with a limit of 10 000 euros (5$ fees)

I will wait for IB to do autotrading on US stock
