Let’s assume an average stop loss of 30 pips. You haven’t talked about timeframes, so we cannot know what size this should actually be. I’ll base my reasoning on you trading the daily chart, as it is the most commonly used.
Let’s also assume you are using a bare bones risk management plan that consists in risking 2% of your capital on a single trade. That equals to 2 dollars when you open the account.
Let’s also assume the average value of a micro lot is going to be 10 cents. Again, you haven’t talked about which pairs you are going to be trading, so I have no idea how much a pip is actually going to be worth to you. 10 cents a pip per 1000 units seems to be reasoneable for major pairs.
For starters, you cannot properly trade like this. Using one micro lot and 30 pips stop loss, the minimum position size you can risk is 3 dollars, which is 3% of your account. I know “just one percent is not much” is something you might think, but look at it this way: you are not risking one more percent; you are risking 50% more than what you planned. That is huge.
Even more huge when you slap two micro lots on. Your minimum position size becomes 6 dollars, which equals to 6% of your account and an absurd 300% increase in your planned risk.
So, the first conclusion is that, if you are willing to trade a single micro lot, you can expect to make roughly 6 dollars on a single good trade. A trade can last anything between a few hours to a couple of days, so we’ll just say you’ll make about 2 dollars per day, on average, on a single good trade.
However, you are going to have bad trades. Many good traders still lose 3 times out of 10. Assuming you make 100 trades, with an exceptional winrate of 70% - that you are not going to get as a beginner -, and assuming proper risk to reward ratio of at least 1:1.5, you are going to lose 90 dollars and gain 315 dollars, for a net profit of 225 dollars.
Assuming a more realistic winrate of 50%, you are going to lose 150 dollars and gain 225 dollars, for a net profit of 75 dollars.
My suggestion is to not do that.
Stick to a demo account, and then move to a live account on a broker that allows nano lots. I won’t suggest one, as you might thing I have commercial interests, but a quick search will give you what you want.
