just put an order on what price you want to buy and gg? easy than that there is not, bit need to be programmed right with the right strategy but should buy any amount in ms

Yes, but it would be great if you could automate a trading strategy (ie: buy if the price hits X and sell if the price hits Y)

You can try Gunbot: https://bt.irlbtc.com/view/1715214.0

It supports Polo, Bittrex and Kraken and you can set it to make buys at a given price.

Edit: BTW Gunthar is quite helpful and you can find a lot of howtos on the Gunbot forum: https://gunthy.org/

Yep! CAT is the most famous and Leonardo also seems to be a good one, but I never tried those, so I don't know if this functionality is present or not. I'm using Gunbot and did this with it.

Gunbot may work well for you, it work in seconds tho, not miliseconds.
You can buy it from Gunthar in this topic (As already pointed by Snail2)
https://bt.irlbtc.com/view/1715214.0

The topic focus on Poloniex, but now it works on Bittrex and Kraken too. Also it's one time fee, you wont have to be paying for using a service, you will be buying the product and run in you PC if you want.

You can use my referral code [REMOVED] for 10% discount. If u need any help setting things up or have any doubts you can PM me, or find me in telegram. (Contact in my profile)

EDIT: Sorry, haven't notice someone already advertise his referral here. I'm removing mine. Altough, I think Gunthar did set some rules about discount, so you may want to check that.

ALSO: On a second reading, I think OP is looking for a method/bot to buy a coin faster when notified by a pump group. If that's the case, gunbot won't help.

Those bots that make bid wars and one up you in 1/10th of a second are annoying. But those bots are fun to game because if I am trying to sell something I can just do a big war with the bot and make It reach its limit fast and than dump on it.

Bots are for the lazy trader, fodder for sharks.

i don't think a fast order execution as soon as price changes is possible on bittrex because they do not offer any socket connections and you will have to get the orderbook manually by sending a simple REST request each time you want to update it and there is always a limit on how many times per second you can do that before your IP is banned!

so there will be a delay unless you contact then and ask them to remove your limits.

what others keep saying about GUNbot is most probably only true about poloniex since it offers sockets which if that bot is using means an open and constant update of the market (orderbooks) as they change so it is live changes with no hassle and you can execute the orders as fast as your internet connection allows you.

the same will be true about any other exchange that doesn't offer sockets which is nearly all of them!

you can buy the coins immediately as long as you have btc to to buy it , if you want to buy coins using bot you would need to set the bot what coin and what price to buy but bittrex have already this which is bid
