Hi,
If i purchase any indicator or EA from market MQL5. Upto how many trading account i can able to use it?
In as many as you want on the computer(s) that you have installed it.
Activation is per computer (with hardware and OS).
So, it can be any trading accounts for 1 activation within 1 computer.

Best way to monitor EA execution remotely

If it is about the Market so the buyer can use EA according to the number of the activations which are linked to the PC and OS:
Rules of Using the Market Service -
13. The number of free Product Activations available to the Buyer on another PC after purchasing the Product is defined by the Seller. The minimum number of such Activations is 4.
14. The Buyer purchases the right to activate a Product as many times as specified by the Seller at the moment of purchasing or renting this Product. For example, if a Product allows 20 activations at the moment of its purchase, the Buyers can install it on 20 different hardware configurations even if the Seller will decrease this number afterwards.
So, 1 activation = unlimited using on 1 PC (one particular computer - hardware) with one OS (Operating System, for example - with Windows 8.1).
For example, if I buy your EA via the market with 1 activation so I can use it on one my PC only with my OS (Windows XP for example) only. And I can not use EA on the other computer, and I can not use EA with same computer with different OS. So, this is the protection: even if someone can get your EA remotedly (from you or from the buyer) so he/she can not use it: he/she have to buy this EA with the activation fro the market (from you for example).
If you question is related to the coding/programming so sorry (I can not help) ...

Means i can able to use EA/Indicator purchased from MQL5 to unlimited PC & Trading account simultaneously. Right?

This ridiculous, What if my PC crashed or Want to use with VPS etc. I need to purchase the license again & again?
It think they should limit trading account (Simultaneously) not PC/Devices.

They are limit by PCs.
Because if you have 8 or 10 activations so you can use it on 8 or 10 PCs (with as many Metatraders/trading accounts as you want).
As to VPS so - activation will not be lost in case you use MQL5 VPS (according to MQL5 VPS rules), but this kind of VPS is mostly for autotrading for example.
And read Market service Rules here.

I am posting this suggestion all the time on the forum. It is related to the Signals, the Market, and to the Freelance as well -

There is one rule which some people follow:
subscribe to the signal or create an order in Freelance or purchase the product from the user/seller/coder/provider you know in person or you know by activity on the forum.
Because if you purchased something so I may ask:
"Do you know the seller in person, or you are familiar with him on this forum?"
If you say: "Not" so it will be very strange case for me ...
----------------
There are a lot of professional and honest users/coders on the forum, and some of them are very active on this forum helping to the other people and replying on the forum posts/requests.
Always choose the person you know in this forum (who is very active here), and you will have much less problems with anything.
Just my opinion sorry (because I am not a coder, and I am using Freelance as well).
What if the VPS from other hosting provider not MQL5 VPS?. Do still same rules applied?
