# Tips on Managing and Calculating Position Size

Determining your position size is an integral step to trading. To enjoy ‘longevity’ trading the market, prudent position sizing is a must.

1. Are good at trading but somehow always lose big.
2. Can score 3-4 winners each time but end up with net loss because of 1 loser.
4. Have the uncanny ability to overweight one single loser and underweight multiple winners.

This is a part of the Tflow® course program.

## How to determine Position Size?

1. How much is your current capital?
2. Percent of capital you’re willing to risk for this trade. (x% multiply by capital)
3. Amount of risk (SL) for this trade.

To calculate your maximum possible position size, take Percentage of capital risk (#2) and divide by Amount of risk for the trade (#3).

Note that for the calculation: 0.1 = micro contracts, 1.0 = mini contracts, 10.0 = standard contracts.

### Example #1

There is a trade on EURUSD with a determined SL of 50 pips from entry.

1. How much is your current capital? \$10,000
2. Percent of capital you’re willing to risk for this trade. 2% x 10,000
3. Amount of risk (SL) for this trade. 50pips

Therefore for this particular trade, 200 / 50 = 4, I can trade a maximum of 4 mini contracts for this trade.

It is important to note that you should always have a total amount of your total capital you are willing to risk for all your trades combined.

Assuming, at any point I’m only willing to risk a maximum of 5% of my total account and I have 3 trades I wish to take then I have to allocate my risk per trade. Below are some examples.

1. Split 5% up as 2%, 2% and 1%
2. Split 5% equally (almost) 1.7%, 1.7%, 1.6%

Calculating your position size in this way, you should not exceed your allocated capital.

### Example #2

Assuming the below conditions.

• Current capital = \$13,520
• Total percentage to risk for all trades = 5% of total capital

I have 3 trades to enter.

With calculation based on the above information, our position size for each pair should be as follows.

• AUDUSD
• (1.6% x 13,520) / 78 = ~2.7 minis
• USDJPY
• (1.7% x 13,520) / 88 = ~2.6 minis
• WTI
• (1.7% x 13,520) / 201 = ~1.1 minis

Hence, assuming that we profited on AUDUSD and USDJPY and got stopped out of WTI.

• \$216 + \$260\$222 = \$254
• In the end, we should reflect a profit of \$254.

### Position Sizing helps to keep you trading longer

By calculating your position size in this way and being aware of the amount you’re risking per trade, this will help to prevent over-trading and improve your chances of overall success in trading.
