Algo trading code for Indian Brokers

I have the following requirements which is fairly simple; I would need someone who has experience in alog coding (python or C#)

I have not selected the algo broker so you can suggest me the best based on the following criteria and you can code on that

1: My Algo should run from my PC. Not on the cloud, not on UI provided by algo trader
2: Algo is related to BANKNIFTY option buying. So, the script should be able to get the options price
3: Algo will work on BANNIFTY spot price.

Algo with check my funds on broker account (Ex: 20 thousand)
Now, from 9:15 algo will check the banknifty spot (you don't have to implement the logic here, just get the values of banknity spot and some values like HIGH 9, or close 9
Now, code blocks for buying and selling.
Buying when condition met (you don't have to code the conditions, just write the code to buy options based one expiry and capital)
Buy more based on remaining capital if conditions met.
Sell code block will sell the options based on criteria.

Ex format:

- Take banknifty values
- Take indicator values

If(condition met)
{
buy options based on capital
}
if(some condition met)
{
add more lots based on remaining capital
}
If(condition met)
{
Sell 50% lots
if (some condition met)
{
sell more 30% lot
}
else
{
sell remaining 20% lot
}
}

Note: you don't have to code the logic and calculation involved in conditions.

You can come up with the suggested broker who can provide API which can give the above data.and allow me to run code my PC.

Bid near 5-7k will have a high probability of getting picked.
