Here is a formula to work out what it takes to grow your grubstake a thousand fold... this is a valuable formula that will help you work out how much you need to win and to set stops at a suitable level.
The inputs are:
S = how much you start with
E = how much you end with
W = number of winning trades
L = number of losing trades
U = average % of each winning trade
D = average % of each losing trade
For those not familiar with the mathematical syntax, * (asterisk) represents multiplication, and ^ (carat) represents to the power of, and / (forward slash) represents division
The formula is:
S * [(1 + (U/100)) ^ W ] * [(1 - (D/100) ^ L ] = E
So let's say you start with £1000, win on average 10% on each trade, and lose on average 3% on each trade. How much will you have after 100 trades with a win ratio of 30%? Then just enter the required inputs into the formula:
S = £1000
E = ?
W = 30
L = 70
U = 10
D = 3
£1000 * [(1 + (10/100)) ^ 30 ] * [(1 - (3/100) ^ 70 ] = E
~
£1000 * (1.1)^30 * (0.97)^70 = £2069.20
You can change the inputs for different scenarios:
Let's say you set stops which if triggered results in loss of 5% of your balance, and your win ratio is now only 20% (e.g 2 wins out of 10 trades), and your average win is still 10%, how much will you have now after 100 trades?
~
£1000 * [(1 + (10/100)) ^ 20 ] * [(1 - (5/100) ^ 80 ] = E
~
£1000 * (1.1)^20 * (0.95)^80 = £111.11!
As you can see, small changes can be the difference between winning and losing! In this case, a win ratio of only 2 out of ten and a slightly bigger stop loss of 5% results in large losses, whereas a win ratio of 3 out of ten and a 3% stop loss results in more than doubling your money after 100 trades. Both scenarios, however, assume you take 10% profit on each winning trade. You can change the values of W,L,U,D to see the changes in the final result.
Now you can use the formula to answer a question like: With a win ratio of 20%, How much do I need to win on each winning trade to break even after 100 trades using 5% stops?
We now want to find the value of U:
£1000 * [(1 + (U/100)) ^ 20 ] * [(1 - (5/100)) ^ 80 ] = £1000
Doing a bit of algebra:
Let (1 + (U/100)) = X
£1000 * (X)^20 * (0.95)^80 = £1000
(X)^20 * (0.95)^80 = £1000/£1000
(X)^20 * (0.95)^80 = 1
(X)^20 = 1 / (0.95)^80
LOG (X)^20 = LOG (1 / (0.95)^80)
20 * LOG (X) = LOG (1 / (0.95)^80)
LOG (X) = [LOG (1 / (0.95)^80) ] / 20
LOG (X) = 0.089105578
Inverse the LOG to get 1.227737663
To test the answer:
£1000 * (1.227737663)^20 * (0.95)^80 = £999.99
X = 1 + (U/100) = 1.227737663
(U/100) = 1.227737663 - 1
U = (1.227737663 - 1) * 100 = 22.7737663
So we now know that we need to make 22.77% profit on each winning trade to break even after 100 trades with a win ratio of 20% and setting stops at 5%.
If you haven't got a scientific calculator with a LOG function you can't answer questions like this.
If you can spot any mistake please let me know. Knowing stuff like this is vital if you want to win!
