The New Trading Rules of the PSE

On July 26, Monday, a new trading system takes over the PSE. I was still a baby (or probably still being made) when the existing system was already in place so I don't have any reactions - positive or negative - towards the new system. All I know is that there is silent (?) dissent from some brokers and traders about the new system due to its impact on day traders and traders in general.

The new trading rules are available at the PSE. Of course, reading through the report will test a bit of your patience if you're not someone who likes to go through all the details. Personally, what I found interesting and quite important is the change in the fluctuation table. Specifically, the board lot used to look like this -

PRICE MINIMUM FLUCTUATIONS BOARD LOT
0.001 to 0.0024 0.0002 1,000,000
0.0026 to 0.0050 0.0002 1,000,000
0.0055 to 0.0100 0.0005 1,000,000
0.0110 to 0.0250 0.001 100,000
0.0260 to 0.0500 0.001 100,000
0.0525 to 0.1000 0.0025 100,000
0.105 to 0.2500 0.005 10,000
0.2600 to 0.5000 0.01 10,000
0.5100 to 1.000 0.01 10,000
1.020 to 2.500 0.02 1,000
2.550 to 5.000 0.05 1,000 **
5.10 to 10.00 0.10 1,000 *
10.25 to 25.00 0.25 100
25.50 to 50.00 0.50 100
50.50 to 100.00 0.50 100
101.00 to 250.00 1.00 10
252.50 to 500.00 2.50 10
505.00 and up 5.00 10

By Monday, the board lot will look like this -


Notwithstanding the obvious difference in graphic layout, you will notice that the price fluctuations are a lot lot smaller now. For example, before, a stock with a price of 20 pesos would change every 25 centavos, such that a typical stock posting would look like this -

Bid Ask
10,000 20.00 20.25 5,000

Now, with the new system, a stock with a price of 20 pesos would look like this -

Bid Ask
10,000 20.00 20.05 5,000

What's the relevance?

Well, from an amateur stock trader's standpoint, depending on your broker, you already have a small profit with just ONE fluctuation if you were trading under the old system.

Now, assuming it's the same stock, you'd have to wait FIVE fluctuations just to get to the price of 20.25 for a profit with the new system. Further adding to the "difficulty" in making a buck is that there will be trading price limits based on what they call the Dynamic Price Threshold.

If I understand correctly, a stock will be frozen (i.e. temporary trading halt) once it hits its lower or upper Dynamic Price Threshold. Based on the information I got from Citiseconline.com -

The Dynamic Price Threshold** is computed as follows:

- Dynamic price threshold (upper) = last traded price + (last traded price multiplied by the dynamic tick)

- Dynamic price threshold (lower) = last traded price - (last traded price multiplied by the dynamic tick)


Example:

If the last traded price for stock A is 5.00 pesos and it has a PSE defined dynamic tick of 0.05 then:

- Stock A dynamic price threshold (upper) = 5.00 + (5.00 x 0.05) = 5.25

- Stock A dynamic price threshold (lower) = 5.00 - (5.00 x 0.05) = 4.75

I don't know why it's called a dynamic tick or if there's any connection to the dynamic duo, but this would make trading a bit, well, harder.

Without going further into the other details of the new trading system, this is the big question - Will the PSEi resume its uptrend come next week? The timing, at least to me, is off-putting. The ghost month is just over the horizon and based on my limited trading experience, is one of the bear months of the local market. It usually lasts until October before mounting what is known as a Santa's rally.

More importantly, will chart reading still be useful? I mean the price ranges now are different from the ones before. Will the prices of before be of any relevance to its future price action?

All these questions will be answered in the next few months, as old traders find ways to do new tricks and new traders probably adopting a wait-and-see mode.

I suppose given this, the market will most probably move sideways. I am not sure since I'm no fortune teller. Well, nobody said change was easy. I just hope that this is for the good and the new system would increase liquidity and volume of the market. If you think about it, volume would certainly pick up since based on my example, a trader will have to buy five fluctuations of a stock just to get to his profit target price.

Let's hope for the best.
