Based on your question asked here, I will suggest you read up FSM's FAQ if you are interested in their platform and wanting to know their process (do the same foe other platform as well)
For example:
https://www.fundsupermart.com.my/main/faq/0...ying-Funds-1605Q: WHEN WILL I KNOW ABOUT THE PRICE I GET?
» Click to show Spoiler - click again to hide... «
A: Most of the unit trusts in Malaysia are priced based on "forward pricing". This means that if you transact today, you will get the fund’s value as of the closing price of the market today. However, you will know the price in two working days
The price that you could see in the website is the so-called 'indicative price'. This is usually the price of the fund two working days ago. This indicative price is NOT the actual transaction price of the fund that you are buying or selling.
Generally, the fund manager requires approximately two business days to consolidate and derive a unit price for the funds. These prices are further valued independently by the fund's trustees. Therefore, the dealing price will be made known to the public two business days after the transaction date. Once we obtained the price, an email notification will be sent to you.
Q: WHEN WILL MY BUY ORDERS BE COMPLETED?
» Click to show Spoiler - click again to hide... «
A: Generally all cash orders will be completed within four business days (T+4) from the day they are transacted.
The transaction cycle for EPF Account 1 will generally take longer time to process compared with cash subscription. Although the transaction date(T) for most fund subscriptions through EPF Account 1 would be the same business day which the required documents are received by Fundsupermart before 3pm, (except AmBon Islam, TA Income Fund and funds under the management of Pheim Unit Trust Berhad),the orders will remain in processing status until the confirmation of successful EPF Account 1 withdrawal.
Once the transaction cycles are completed,your units will appear under your holdings.
All units are priced on the transaction date (T).

Generally T+4 business days for all other unit trusts.
'T' date is the day where your sell order is transacted. You will be notified of this via an email. There are three methods for us to credit the proceeds to you:
1) Cash Management Fund:
When you sell a unit trust but want to wait before you buy another, you may park the sales proceeds in the Cash Management Fund first.
You may indicate the “Cash Management Fund” as the redemption method when you sell. The sales proceeds will be used to buy into the Cash Management Fund on the settlement date of the sell order.
To know more about the Cash Management Fund, click here
2) GIRO Transfer:
If your bank account is opened in Malaysia, we will transfer your redemption proceeds directly into your designated bank account on Settlement Date.
To update your bank account, go to MY INVESTMENTS-> UPDATE ACCOUNT-> REDEMPTION INSTRUCTION.
B: For EPF Account 1:
The redemption proceeds will be credited back into your EPF Account 1 within 10 business days by the fund manager.
https://www.fundsupermart.com.my/main/faq/1...g-of-Funds-8922Q: HOW LONG WILL THE WHOLE INTRA SWITCH PROCESS TAKE?
» Click to show Spoiler - click again to hide... «
A: Cash investments
The switch-sell and switch-buy orders will be transacted on the same business day the order is received before 3pm. Otherwise it will be transacted on the next business day.
However, please note that there are 2 business days lag time should you switch buy into RHB Money Market Fund, RHB Income Fund 2, RHB Institutional Islamic Money Market Fund and 1 business days lag time if you switch buy into CIMB-Principal Equity Growth & Income Fund, CIMB-Principal Greater China Equity Fund, CIMB-Principal Income Plus Balanced Fund, CIMB-Principal Global Titans Fund, CIMB-Principal Australian Equity Fund, CIMB-Principal Strategic Bond Fund, CIMB-Principal Asia Pacific Dynamic Income Fund, AmSchroder European Equity Alpha Fund and Kenanga Asia Pacific Total Return Fund.
EPF investments
The switch-sell and switch-buy orders will be transacted on the same business day the fund manager in-house switching form is received before 3:00pm. Otherwise it will be transacted on the next business day.
NOTE:
The whole process of an Intra switch (for BOTH cash and EPF Account 1 investments) will take four business days to complete after the transaction date (T) of the switch sell & buy funds i.e. T+4 business days.
Q: HOW LONG WILL THE WHOLE INTER SWITCH PROCESS TAKE?
» Click to show Spoiler - click again to hide... «
A: The switch-sell order will be transacted on the same business day the order is received provided the order is received before 3pm. Otherwise, the order will be transacted on the next business day.
The switch-buy order will be transacted based on the lag time as described in the table shown at FUNDS INFO-> FUND SALES CHARGES-> SWITCHING-> INTER FUND HOUSE. However, this lag time will be shorter than executing the sell and buy transactions on your own.
NOTE:
The whole process of an Inter switch will take four business days to complete after the transaction date (T) of the switch-buy funds ie T+4 business days.
Take some time to read the FAQ, grasp the basic terms and process gradually, you can also experience them by using small amount.
From there, you can gain more confidence on your understanding in the overall transaction and pricing process

At least my experience on M2U was buy Wednesday early morning and get on Thursday evening. So no idea why FSM taking four business days. Plus most funds priced at T+1 right? Like tomorrow they will publish today's prices. How is it T+2 as FSM claims?
