Please just focus on the amount of slot sizes
please elaborate. do you mean what type of account, or lot sizing. If you meant account types I have done the math and you stand to reduce transaction costs by approximately 33% by opting for a brokerage’s commission razor spread account as opposed to a standard spread account. For example say you are buying and selling 1 standard lot (100,00 units) on a standard account, on most majors the spread is on average 1.5 pips during normal trading conditions. So round trip (buying and selling) you are losing 3 pips of unrealized movement which would equate to $30 dollars on 1 lot. Now say you were using a commission account with reduced spreads, most i’ve seen charge $10 round trip and they have average spreads of .5 pips. So now after buying and selling 1 lot you only have 1 pip of unrealized movement which equates to $10 and your round trip commission is another $10 making your total cost $20. This example scales linearly and some brokerages will cut commissions even smaller if you trade enough volume. So I believe you should always opt for low spread commission accounts. If you meant what size to trade as a beginner, well thats completely variable to your strategy, SL placement, and account size and I’m not sure I can give a definitive answer. What I will say is beginner or not it’s probably best to not lose more than 1% on 1 trade so that being said if your SL is 10 pips away and your account size is $1000 I wouldn’t put more than .1 lot (10,000 units) of size on. Hope this helps! (My dollar amounts are in USD)
