October's INJI sales were 17 units and 39,798 yen — a month where the MT5 version accounted for more than 40% of revenue before, during, and after the 500 yen discount campaign

I am lab.aiueo, creating MT4/MT5 indicators and selling them on GogoJungle.

I publish monthly sales figures as numbers. This is for October.

To start with the conclusion.

This month, most products were discounted by 500 yen for a limited time. The focus of this article is comparing sales before, during, and after that period.

First, the daily unit count increased during the period, but only by 4 units. Since such a difference can occur naturally about once every 4 times, I cannot yet say it was “effective.”

October results

All amounts are receipts after deducting fees and affiliate commissions. October numbers are as of noon on the 31st. September numbers are up to the 29th, and the September 30th figures are not included in either total.

Cumulative since April: 105 units, 251,706 yen.

Buyers totaled 15, up by 3 from September’s 12. Units remained 17, and revenue rose 6%.

What sold in October

The largest numbers were 4 units each for SMC-Signal MT5 and SMC-Radar (MT4).

The 4 units of SMC-Radar are the most since August, tied for the highest. Of those, 3 were sold at regular price after the campaign ended.

SMC-Signal (MT4) was 3 units. After dropping from 21 units in June, it rose from 2 to 3 in September.

Did the 500-yen discount work?

From October 18, 19:00 to October 23, 23:45, most products were discounted by 500 yen. Using the “Campaign sale” feature on the GogoJungle seller dashboard.

Sales before, during, and after the period are as follows.

The daily units were 0.45 before, 0.77 during, and 0.62 after. During the period, the daily units were higher.

However, only 4 units sold during the period.

If the non-campaign days’ pace is applied, this 5-day window would sell about 2.6 units. Selling 4+ units in that window happens about 1 in 4 times even without any effort. This single occurrence cannot determine whether it worked or was a coincidence.

Impact of discount on take-home pay

Discounts reduce the money left in hand.

The 4 units during the period were all via affiliates. Take-home is 55% of the selling price, so a 500-yen discount reduces take-home by 275 yen per unit. 4 units mean 1,100 yen less.

If the increased sales are truly due to the campaign, the increase would be about 1.4 units. In take-home terms that’s about 2,500 yen, so the 1,100-yen discount is offset. If it’s coincidence, you’ve just reduced 1,100 yen.

We won’t know which until we try again several times.

A customer who bought at list price 8 hours before the campaign started

One thing stood out.

Eight hours before the campaign began, at 11:00 on October 18, a customer purchased two units at the listed price.

In September I wrote that I would not discount. It wouldn’t be fair to those who bought earlier. This time I kept the price the same and ran a time-limited campaign, but such cases do occur. When discounting, I need to consider this weight as well.

Unseen discount outside the campaign

Three units sold before the campaign were slightly below the 55% take-home rate.

• October 4 SMC-Signal (MT4) … 150 yen less
• October 11 CP-Signal MT5 … 136 yen less
• October 12 SMC-Signal MT5 … 248 yen less

Total 534 yen. These are not discounts I offered. With GogoJungle coupons, sellers bear up to 50% of the discount, so I assume that amount.

Here, a correction to August’s article.

In August I wrote, “With convenience store payments, further discount of about 191 yen occurred.” Looking again at all cases since April, four out of five convenience store payments had exactly 55% deducted; only one case was discounted by that amount. I now believe this was due to coupon burden rather than payment method. Apologies for the error.

MT5 version revenue exceeded 40%

Share of revenue by MT5 version.

• July: 21%
• August: 36%
• September: 37%
• October: 42%

In October, 7 of 17 units were MT5 versions.

OANDA Securities’ MT4 service ends on November 27. New orders already stopped as of September 25.

CP-Signal MT5 released the day after a request

In October, I listed two new items. The first is CP-Signal MT5.

A buyer of SMC-Signal MT5 emailed that they were hoping for CP-Signal MT5. I started porting on October 9 and listed on the 10th.

Rather than simply porting MT4, I fixed issues I had noted in MT4 while porting.

• Read other currency pairs by time, not bar count
• Judgment of past sessions based on summer time at the time of that bar
• Measure price movement dispersion using 500 bars up to startup, not just once at startup
• Make current judgment and past reproduction use the same processing for session judgment
• Automatically read suffixes of currency pair names

All are fixes to avoid using information that shouldn’t be known at that time when drawing signs on past charts.

Two units sold in October, both to customers who had previously purchased other products.

Also, CP-Signal MT5 and BT-Replay sold two copies of MT4 CP-Signal that had sold 0 copies in August and September. The reason is unknown.

BT-Replay revealed a bug in my tool

The second item is BT-Replay, released on October 11. It’s a tool to replay past charts one by one in MT5 for practice and verification of discretionary trading. One unit sold in October.

While filming the SMC-Signal MT5 introduction video with BT-Replay, the sign for SMC-Signal MT5 did not appear on the chart being played.

The cause was on the BT-Replay side.

BT-Replay rewrites the 1-minute bars confirmed during playback. Immediately after, when MT5 asks which bar this time corresponds to, it may fail. SMC-Signal MT5 failed to produce a sign due to that failure and stopped until the next sign in the same direction appeared.

I corrected it to locate the bar position from my data and released Ver1.03 on October 17.

This is discovering a bug in my prior tool via my new tool. I also released BT-Replay Ver1.01 on October 17 due to another flicker issue when running fast, as noted on BT-Replay.

CP-Signal MT5 and BT-Replay are both 3,980 yen. Prices as of October 31, 2026. May change.

A customer who bought the second copy

Among the 15 buyers in October, 3 had purchased before September.

• After SMC-Signal MT5, CP-Signal MT5
• After SMC-Signal (MT4), MT5 version of the same product
• After buying 5 SMC series, 6th copy CP-Signal MT5

Since April, among 76 customers, 17 (22%) bought 2 or more copies, accounting for 42% of revenue from those customers. It rose slightly from 40% at end of September.

Thank you, as always.

Sold on Saturday for the first time in four months

Since July 4, Saturdays had not seen a sale for 16 consecutive weeks. I planned to say that in this article as well.

However, on Saturday noon, October 31 (the day I’m writing), SMC-Signal (MT4) sold one copy. It had been four months.

Out of the 105 copies since April, Saturdays account for 3 copies. It remains that sales are harder when markets are closed, but I can’t say “it doesn’t sell” anymore. Thank you to the buyer.

What I did in October

• October 3: Started a series on note
• October 10: Released CP-Signal MT5
• October 11: Released BT-Replay and published an introduction video on YouTube
• October 17: Released SMC-Signal MT5 Ver1.03, BT-Replay Ver1.01, and published SMC-Signal MT5 introduction video
• October 18–23: Limited-time campaign

The introduction video is embedded on the product page as well. Its impact on sales is not yet known.

Looking toward November

OANDA Securities MT4 service ends on November 27. I will verify how far the share of MT5 increases using November’s figures.

November figures will be published at the end of the month.

Thank you for reading to the end.

Wishing you good trading.
