From what you have written you have very limited knowledge about algo and quant trading. Let me correct you.
I am not sure what you mean by scalping robots, because most HFTs are scalping. If your term is limited to MT4 robot, then I am not sure.
Some algo or quantitative trading do not use volatility as their variable, their strategies discount volatility, hence volatility does not affect their trading.
It does not matter how many percent it represent, even it is it 1%, you can still access the order flow. You clearly do not understand how futures and spot forex work and how they are separated. Why you want to know the real volume in the first place when you already have forex futures with depth of market?
Your programmer friend is probably an amateur who works with MT4 without the knowledge of other platforms and knowledge of quantitative/algorithmic trading. Tweaking will only curvefit the robot, that's where your friend went wrong.
Again you are talking about huge stoploss and small stoploss. I recommend you to read more on quant and algo trading then we can talk at the same level/frequency.
Scalping robot refers to mt4 based. I'm saying that those technical based bots on mt4 doesn't work for long due to changing volatility because most of it rely on technical entries like breakout, moving average cross over.
So they tune the bots to follow certain market conditions for trade but then can't work as well when volatility changes.
Unless the bots are using very wide SL.
Over the years I see those bots making money for a couple of months which later account burnt due to changing market conditions n volatility. That's why broker use bots to lure ppl to use robots because most of the time confirm lose after a while.
The big guys HFT is all based on front running orders. Or practically speed and also order based. (Quant or algo trading the only thing which works if not those big guys won't dump in tune of hundreds of millions)
Regarding futures and spot fx.
For every single tick the value of transaction is different.
Futures are based on contract, every tick represents a fixed contract size.
Real exchange ticks are based on a variable contract size. 1 tick=usd 100mil during active hours. During non active hours maybe 1tick=usd 10mil. Transacted amount is unknown behind every tick. The exchange do sell these data for premium price
MT4 is a time based price platform. Moving average is time based rather than tick/volume based.
