Standard LotMini LotMicro Lot
Denoted As 1.0 in MT4/5Denoted As 0.10 in MT4/5Denoted As 0.01 in MT4/5
100,000 Units of Base currency10,000 Units of Base currency1,000 Units of Base currency
Pip Value $10 For USD PairsPip Value $1 For USD PairsPip Value $0.1 For USD Pairs

To simply calculate the lot size you should take it just clarified with the formula of equity multiply by percentage of risk you are willing to take and divided by the pips you are gonna setup the stop-loss which will identify the position size or lot size for your trade(To identify the margin you required for remains opening your trade while a position is against you until it goes to your favor or hit stop-loss) to understand more clearly here is the example below.

Equity×%Risk/No. Pips = Lot size

Let’s take a fictionary Account of USD currency having the Account balance/equity of $100 and ideally and preferred risk tolerance should be on per trade is more than enough and seasoned approach is 1-2% and we take the high percent and take 2% of risk which will be in the amount $2 and which mean I am ready to lose $2 if my trade goes wrong which will be worse case scenarios hit stop loss.

Now, what should by using the rule to calculate lot size by dividing the $2 on the number of pips where my stop loss will trigger which is for example currently EURUSD is on a price 1.18333 and I am gonna buy it at this exact price and my stop loss will be exactly below the price of 1.18161 just below the hourly support and which give me 172 pips stop loss so to know the exact lot size I should divide the amount of risk $2 on the numbers of pips which will be calculated as equals to 0.0116279069767442 and the final lot size will be simple As Micro Lot 0.01 can be taken On my account as a good money management rule.

Hope the above calculation not cause you confusion, try to clarify you lot size concept because it is the great fundamental for retail traders to avoid psychological-emotional in-discipline and give you the right path while trading and understand you to make the right trades in the right direction instead of imaginary trades illogical lot sizes and account wipeout from the equity in a single trade as beginner understanding lot size and maintaining and calculating it according to rule in your trading give you more breathing room and consistency in the trading journey along with suitable steady income instead of get rich quick too much risky techniques.

Unknowingly if you divided the risk amount to No. of pips and get the value below even the micro lot For Ex: 0.009 or 0.003445 something then there is an issue that you have to understand you cannot set stop loss too far away from the position if your equity equals to $100 or below according to the leverage you have taken. Ideally and even recommendation is that the 1 pip value of a micro lot is $0.1 and the 2% risk No. of pips will not bigger than the 20 Pips. If you want to set stop loss far away from the position too long to remain open in negative then you have to (extremely discouraged this approach) increase your risk percentage/amount or top up your equity/account balance to get a suitable lot size for your trade within 3 market standards.
