Let me quote the example here
I bought 100 shares @ 17.7 since brokerage per share comes out to be less than 0.1 per share i am being charged Rs 10 + tax components where brokerage is Rs 10
However when i set the %of trade value to 0.47% (ie;0.3% + tax component) and 0.1 for the min amount Amibroker calculates my commission as Rs 8.319.
Hello,
Now I got you. Here is the solution, in AmiBroker Account Manager itself. AmiBroker Account Manager has 5-tier commission levels to suit to your needs. When none of the tiers are used, the default is used. In your case, we will have to use 2 tiers, first one for charging Rs.10/- commission for all trades where commission works out less than Rs.10/- and 2nd tier, when commission value exceeds Rs.10/-.
To do this setting, go to File>>New>>Account. Go to summery tab first, expand Commission Menu and define first tier. Here we find that till the time transaction value is less than Rs.3333.33, commission should be set to Rs.10/- so we set tier unit as Transaction Value, tier min. as 0.01, tier max. as 3333.34 and per trade as 10/-. What it means is : till the time tier unit (transaction value) is between tier minimum (0.01) and tier maximum (3333.34), per trade commission of 10/- will be applicable.
Once done, now we move to tier 2 to define scenario for transaction amounts greater than 3333.34. Here we define Tier Unit as Transaction Value, min. as 3333.34, tier max as 100000 and % of trade value as 0.3%.
(Please note that this tier max you can put as per your actual tier limit, say if your commission decreases to 0.2% after your transaction value crosses 100000, you will put 100000 here in tier max and will define another tier 3 from tier min 100000 to further amount to have per trade commission as 0.2% and so on).
Once this is done, fund your account, and try a sample purchase. You will notice that your commission amount will be automatically set to 10 when transaction value is less than or equal to 3333.34 and once it crosses 3333.34, commission will be calculated @0.3% till 100000.
See the settings screenshot enclosed.
I hope this helps.
