Bet size or bet stake is the amount of money you bet per point, correct? How does this work if you are trading futures when you have to purchase a contract at a specific margin? Say I have $8,000 total capital and I want to bet 1/500th of it ($16), how would I place this bet purchasing a futures contract?
1/500th that's kinda low, most future contracts that's like 1 pip / tick / point whatever, 2% so 1/50 $160 is more realistic firstly. Then you need to purchase a futures contract and set a SL which will be X pts away depending on the value per point if the product your trading.
Well it's highly unlikely to trade futures with 16$ trading margin. But if you can't allow more move on CFD from retail forex broker it is the same trade with the same characterstics - profit, loss, but margin is a little less.
