Is Trading on Rollbacks Effective? Part 7. New Zealand

Previous studies of rollback trading have revealed the usefulness of this strategy for a number of economic events in six countries. Let's see if trading on rollbacks is suitable for New Zealand events.

Recall the trading strategy:

If the current value of the indicator is greater than the previous one, then an order is placed

BuyLimit = Open1 – k*Open1

If the current value of the indicator is less than the previous one, then an order is placed

SellLimit = Open1 + k*Open1

where k is the percentage of rollback from the opening price at the time of the publication of the Open1 indicator, 

k = 0,05; 0,1; 0,15; 0,2; 0,25; 0,3.

We wait for 8 hours. If the pending order has not worked, we cancel it.

Closing a position:

1) on close 4, 8, 12, 16, 20, 32 of candlesticks after entering the market;

2) by order TakeProfit (TP):

for buying:

• ТР (1) = BuyLimit * (1 + k)
• ТР (1,5) = BuyLimit * (1 + 1,5*k)
• ТР (2) = BuyLimit * (1 + 2*k)
• ТР (2,5) = BuyLimit * (1 + 2,5*k)
• ТР (3) = BuyLimit * (1 + 3*k)

for selling:

• ТР (1) = SellLimit * (1 - k)
• ТР (1,5) = SellLimit * (1 - 1,5*k)
• ТР (2) = SellLimit * (1 - 2*k)
• ТР (2,5) = SellLimit * (1 - 2,5*k)
• ТР (3) = SellLimit * (1 - 3*k)

If TakeProfit has not worked within 8 hours after the publication of the indicator, then we close the position ourselves at the end of these 8 hours.

A total of 66 entry/exit combinations.

Analysis of the obtained results 

Closing a position on close 4, 8, 12, 16, 20, 32 of candlestick after entering the market

We will evaluate the results according to the following criteria:

• The rate of return reflects the average percentage of changes in the quotations of financial instruments at the time of closing positions in percentage. A positive value of the rate of return indicates the profitability of the strategy, negative - about the loss.

Let's accept the notations for combinations of entry and exit from the market by the number of the candlestick:

Candlestick 4 - exit from the market an hour after the entry.

Candlestick 8 - exit from the market 2 hours after the entry, and so on.

The results are presented in diagrams:

The rate of return of the rollback trading strategy for all events in New Zealand does not reach a significant value of 0.09% modulo with rollback of 0.25% and exit from the market 8 hours after entry. 

In the group of important events, a significant rate of return has been noted for any percentage of rollback and exit from the market 8 hours after entry, as well as for a small rollback of 0.05% and exit from the market 5 hours after entry.

Let's see which of the events and at what combination of the percentage of rollback and exit from the market have shown a rate of return close to 0.09% and higher:

k = 0,05 %

k = 0,1 %

k = 0,15 %

k = 0,2 %

k = 0,25 %

k = 0,3 %

The following events have shown a significant rate of return:

• GDP (YoY) – with a rollback percentage from 0.05 to 0.25 and exit from the market 5 hours after entry.
• GDP (QoQ) – with a rollback percentage of 0.05 and exit from the market 8 hours after entry; with rollback percentages of 0.1, 0.15 and 0.25 and exit from the market 5 hours after entry; with a rollback percentage of 0.2 and 0.3 and exit from the market 4 hours after entry.
• RBNZ Interest Rate Decision – only with a small rollback percentage of 0.05 and exit from the market 8 hours after entry.
• CPI (YoY) – with a rollback percentage of up to 0.15 and exit from the market 5 hours after entry; with a rollback percentage of 0.2 and 0.25 and exit from the market 8 hours after entry; and with a rollback percentage of 0.3 and exit from the market 1 hour after entry.
• Unemployment Rate – with a rollback percentage of up to 0.2 and exiting the market 8 hours after entry, as well as with a rollback percentage of 0.25 and exiting the market 4 hours after entry.
• Employment Change (QoQ) – for any rollback and exit from the market 8 hours after entry.
• NZIER Business Confidence (QoQ) – for any rollback and exit from the market 8 hours after entry.
• Retail Sales (QoQ) – with a rollback percentage of 0.05 and exit from the market 5 hours after entry; with a rollback percentage of 0.1 and exit from the market 8 hours after entry.
• Electronic Card Retail Sales (MoM) – with a rollback percentage of 0.1 and exit from the market 8 hours after entry.
• Business NZ PMI – with a rollback percentage of 0.2 and exit from the market 5 hours after entry; with a rollback percentage of 0.25 and 0.3 and exit from the market 8 hours after entry.
• Westpac Consumer Sentiment – with a rollback percentage of 0.3 and exit from the market 8 hours after entry.

At the same time, in most cases, with a growth in the rollback percentage, the rate of return also increases.

These events are worth paying attention to.

Closing a position on a TakeProfit order

The Take Profit orders are placed because there is a possibility that, having rolled back after the publication of the event, the price will return to the opening level.

We will evaluate the results according to three criteria:

• The rate of return reflects the average percentage of changes in the quotations of financial instruments at the time of closing positions in percentage. A positive value of the rate of return indicates the profitability of the strategy, negative - about the loss.
• % TP - the probability of triggering a Take Profit order, %
• SPP - share of profitable positions, %

The results are presented in diagrams:

Recall that in the first part of our study of trading on rollbacks when exiting the market on a TakeProfit order, we have settled on a rollback percentage of k = 0.1 and Take Profit coefficients: TP = 1.5 and TP = 2.

The rollback percentage of 0.1% has been chosen due to higher rate of return, the probability of triggering Take Profit orders and the share of profitable positions.

Similarly, Take Profit (TP) coefficients equal to 1.5 and 2 have been chosen.

The rollback percentage of 0.05 has been excluded from consideration due to the widening spread at the time of the publication of events, the delay in reflecting data in the economic calendar, and, as a result, the low rate of return of the strategy.

For the coefficient TP = 1, the following has been observed.

After the publication of events, the price may roll back in the direction opposite to the economic meaning of the published events. However, within the next 8 hours, it tends to return to the opening price at the time of the publication of events. And the lower the price rollback percentage, the more likely such a result is.

The results of events in New Zealand also confirm these findings.

A significant rate of return for the selected parameters will also be considered a rate of return of 0.04% or more.

Let's see for which of the events in New Zealand the effectiveness of rollback trading has been identified.
