In terms of taxation, investment platforms are highly efficient and thus attract businessmen and individuals. When you get to such a platform, you have access to a large amount of funds, the terms of sale and purchase of which differ depending on the providers. Investors can also manage multiple products under one roof as most platforms allow ISA, GIA, and SIPP to be used concurrently. You can choose any platform depending on your capabilities and preferences.

3. Cash — these can be different types of accounts with different interest rates. They have the lowest profitability, but significantly reduce risks.

4. Fixed interest is the most common type of investment. Basically, bonds are bonds, that is, a government loan from individuals and the payment of an interest rate in return.

8 Tips to Create a Successful Investment App

An investment platform can have different functions and capabilities. This diversity is due to the goals and objectives that it must fulfill. Let’s take a look at some of the basic tips to keep in mind when developing such an application.

Simple registration

In the matter of finances, registration is indispensable, but it is important to think simultaneously about comfort and safety. Registration should be quick and easy, use biometric parameters, several levels of authentication, but everything should be extremely clear, intuitive and simple.

Provide a personal account

All user actions must be confirmed and displayed in his personal account. He should also be able to edit, delete and add any information related to his profile. It should also contain a large number of settings related to investment operations. All updates should be loaded instantly.

Include a wide range of trading instruments

The platform should offer a clear trading mechanism. This refers not only to the placement of shares, but also to tracking the movement of funds. Provide manual and automatic modes.

The ability to make deposits

Deposits are always a popular feature, which will attract significantly more users. Do not forget to describe the conditions for providing a deposit in the most detailed and understandable way. The process should be transparent and understandable, because your reputation depends on it.

Convenient search

Users should be able to quickly and easily search for active stocks and see their current rates. This will give your product great value and an expert level that will attract not only amateurs, but real professionals as well. The more convenient your product is, and the more money your customers can make with it, the greater your superiority over competitors.

Add analytics

Detailed reports with multiple visualizations will help your clients analyze their own successes and decisions. You can also provide hints as a built-in or optional feature.

Push notifications when needed

Any important changes and news should be communicated to users with lightning speed. The easiest and most effective way to do this is by push notifications. But do not forget to ask the user if he agrees to receive notifications. This is an important point from a legal point of view.

Add a news feed

This function will be useful both for ordinary users who found themselves on the platform for the sake of interest, and for experienced traders with extensive experience. Let them have the opportunity to keep abreast of all world trends and updates in the value and status of the shares they are interested in.

Data Protection in Trading

When developing a mobile application, it should be borne in mind that the data used by this application may be of certain interest to third parties. The value of this data varies widely, however, even the most simple private information, for example, an application login password, requires elaboration of its protection. This is especially important in light of the spread of mobile trading apps like eTrade to all areas of electronic services, including financial, banking, storage and transfer of personal data, and so on.

Pay attention to database security and encryption. Use, for example, an asymmetric algorithm with a private key known to the server. In the case of investment platforms, you can face a lot of scams, and your first priority is to protect your users.

Regulatory Compliance in Financial Services

In short, regulatory compliance is government-defined laws at the state and international level. All companies operating on the territory of states must comply with them when carrying out their activities.

In the case of investment, it is important to ensure that all participants are protected from money laundering and adhere to the Fair and Accurate Credit Operations Act 2003 (FACTA). All this guarantees the integrity of financial transactions and prevents identity theft.

Following all of these rules should lead to a complex but mature compliance scheme for financial services organizations. Any violation of these rules will incur penalties and legal consequences.
