Trading from chart like Interactive broker Buy/Sell option

Hi,

First of all, thank you for such a wonderful community of traders and developers. This is my first post in the forum. I am a developer/aspiring trader and look forward to develop a small feature in Amibroker to check my mock trading skills and experiment.

I need guidance on "How can I code Trading from chart like Interactive broker Buy/Sell option in Amibroker and write trades in log file". As of now, clicking buy/sell and placing trade on chart ask to install the IB plugin. I just want to create a custom feature to write the trades into the log file in case of replay option of amibroker or in live market. I have attached the file to display buttons I am referring to in Amibroker.

I am just looking for hints on how to start on this along with any relevant article/afl to get this done.

Looking for your help and guidance.

Thanks & Regards,
Rajat.

I am experimenting myself and will keep posting my progress here.

Sometime back, I found the following afl from internet. Thanks to the author. I don't remember where I picked up from hence not able to give URL. It comes close however, there are few important things missing.

First I will mention the questions and then the afl here...

Q1 : First I need to drag it like indicator on chart and then I can start putting buy/sell. Rather can it be simply
a button click (like IB buy/sell buttons) or better just use some intitutive methods -
- like single click put the buy while double click put the sell
Q2 : Option to select and drag/drop of same order? How to achieve this.
Q3 : Requesttimedrefresh(1) keep refreshing a lot and in turn not allowing to display the buy hence I changed it to Requesttimedrefresh(100). Not sure, if it will not trigger the order when price crosses this point. Still reading about this method at my end.
