Programming an EA for trading Indices

I think that Indices are more profitable than Forex and I have made an EA. But I am not sure if it is at all possible to calculate the Lot size according to the wanted risk. I have searched Google and Youtube heavily and found only a lot of rubbish. Can anybody point in a direction of a code example of risk management and Lot calculation on Indices??

Does anybody have any experience of programming and trading robots on indices. You will not be asked to share your robot, only your knowledge.

work your SL in ticks and then use tickvalue to work out the risk
from there adjust your lot size to limit your risk based on ticks*tickvalue*lotsize

I think the formula is: balance times risk divided by stop-loss-points, i.e.
balance $1000,
risk 1%,
stop is 10 points from entry, then:
contracts = 1000*1/100/10 = 1 (one contract).

Yes. Thank you very much. I use MQ4 for now and to my knowledge it cannot work at ticks.But I agree that this is the easy way.

Thank you, I will try that.

Sorry guys but until market gets some volatility, Could any one help me in this EA parameters , Its step trailing stop expert but i cant understand how does it work ? I wanna set it to move my SL two pips when price moves 10 pips in my favor.

I will guess that you have to set "Points Of Increment The Current Stop" to 20 (20 points equal 2 pips), and "Points Of Distance From The Current Stop" to 100 (100 points equal 10 pips).
