Yeah I guess it is kinda like. You have 1 btc in total, you give %10 share to 10 pairs. One pair has 0.1 btc volume, you use %20 of it to buy at level1, if it goes down to level 2 you use %30 more and if it goes down to level 3 you buy %50 more using up all remainder of 0.1 at level 3.
If it goes up to level 1 you sell %20 and so forth like buying but selling part.
Is that it gunthar?
Nope: the buy order will always be 1 only. The step gain makes you able to explore deeply down a dump and highest possible in a pump. If a level fails, the bot would buy to the below level or higher.
So:
if you have level 2 to 5% an level 3 to 10%, it will try to reach 10% and if it fails it buys somewhere between 5-10% (depends on volume)
Hope it helped.
