What Is Theoretical Opening?

Ever wonder how does the system decide the opening price of the day? Why it will gap up or gap down?

Exchange uses theoretical opening price & volume to decide the opening price with 4 rules.

R1: Maximum Executable Volume

R2: Establishing the MINIMUM SURPLUS (Lowest quantity shares left in the market)

R3: Ascertaining where the market pressure exists (+ve/ Surplus will remain on the buy side, -ve/ negative will remain on the sell side.)

R4: Consulting reference price (Previous day closing price).

Need to based on the above 4 principles sequence to determine TOP. For example: if R1 doesn’t fulfil, then fall to R2 and follow by R3 and R4.

By understanding the Theoretical opening, it helps us to decide our morning day trade. (link below for our Pre-open market trade.)

What is R1, Maximum Executed Volume?

- Assuming everyone is selling the same type of surgical mask in the market.

- There are 3 sellers, you, Kelvin, Bob & 1 buyer, Lucy.

Buyer	Buying QTY	Price	Selling QTY	Seller
You	2,000	1
Kelvin	5,000	0.90	10,000	Lucy
Bob	5,000	0.80
Total	12,000		10,000

- 10,000 is the maximum the market is able to absorb and at 1 price only. So the TOP will fall under RM1.

- If there are 3 price differences to fulfil the maximum volume, RM 1, RM 0.90 & RM 0.80, then we will be based on R2 to find out which price TO will be. :

Buyer	Buying QTY	Price	Selling QTY	Seller
You	2,000	1	5,000	Lucy
Kelvin	5,000	0.90	2,000	Suzy
Bob	5,000	0.80	3,000	Daisy
Total	12,000		10,000

2nd Principle, R2 (Establishing the MINIMUM SURPLUS (Lowest quantity shares left in the market):

Buyer	Buying QTY	Price	Selling QTY	Surplus	Seller
You	2,000	1	5,000	-3,000	Lucy
Kelvin	5,000	0.90	2,000	+3,000	Suzy
Bob	5,000	0.80	3,000	+2,000	Daisy
Total	12,000		10,000

In the above case, the lowest quantity of shares left in the market is +2,000, RM 0.80. Therefore Theoretical Opening price will be RM 0.80.

However, if there are 2 prices, they have the same lowest quantity of shares which in this case is 0.90, -2,000 & 0.80, +2,000. Then the system will move forward to principle 3 to find out which price will be TO price.

Buyer	Buying QTY	Price	Selling QTY	Surplus	Seller
You	2,000	1	5,000	-3,000	Lucy
Kelvin	2,000	0.90	4,000	-2,000	Suzy
Bob	5,000	0.80	3,000	+2,000	Daisy
Total	9,000		10,000

3rd Principle, R3: Ascertaining where the market pressure exists (+ve/ Surplus will remain on the buy side, -ve/ negative will remain on the sell side.)

Buyer	Buying QTY	Price	Selling QTY	Surplus	Seller
You	2,000	1	5,000	-3,000	Lucy
Kelvin	5,000	0.90	2,000	+3,000	Suzy
Bob	5,000	0.80	3,000	+2,000	Daisy
Total	12,000		10,000	+2,000

If under R2, there are 2 or more price levels that have the same surplus quantity. Then the system will proceed to 3rd principle, R3 to check where the market pressure from.

If the surplus more on is positive, then the pressure is from the buyer side, so the TOP will follow the highest price in the Buy Queue and vice versa.

For the above case, the pressure is from the Buyer side, because the surplus is positive due to Cumulative Buy Quantity minus Cumulative Sell Quantity. Therefore we will take the highest price of Buy Queue as TOP, RM 1 vice versa.

4th Principle, R4: Consulting reference price (Previous day closing price).

Buyer	Buying QTY	Price	Selling QTY	Surplus	Seller
You	1,000	1	5,000	-4,000	Lucy
Kelvin	5,000	0.90	2,000	+3,000	Suzy
Bob	4,000	0.80	3,000	+1,000	Daisy
Total	10,000		10,000	0
