Quote from justrading:
Tom, as I said in my other post, I get clobbered with a 0.01% VAT on my local trades here in Thailand and I still do better than 20% per year on average. No calculation needed, I already pay the tax here and I am talking about my nett result.
Even if I trade FX with Oanda and use the 50:1 leverage (which I would not), for a 0.001% FTT to put me out of business, I would have to average no more than 0.1% profit per trade after commissions (ie 0.001% *50*2 sides). I'm not in the HFT game so if all I made was 0.1% per trade I would quit and leave my money in the bank.
But let's be crystal clear, this is only if there is no cascading or multiplier effect.
If anyone is interested, this is the calculation for a small account.
Capital per trade - $10,000
Trade value @ 50:1 = 10,000 x 50 = $500,000.
Assume close trade at breakeven, round turn value = 500,000 x 2 = $1,000,000
FTT @ 0.001% = 1,000,000 x 0.001% = $10
On capital of $10,000, $10 = 0.1%
Clearly this example does not factor in commissions, so breakeven would be 0.1% + RT commission, beyond that profits.
