Sadly, none of them will work as well as the demos... I always test on live accounts (very small size) before scaling in. Seeing something work in demo and then expecting it to work in live is just a waste of time.. never works especially if you're looking to take a few pips.
IC Markets as far as I know the best for ticks scalper's ea, very low slippage and pretty good execution time. Also I heard from other traders, that it's the best for this type of trading. Wish you profitable trades.
As per my experience of 5 years in trading, I don’t think there is any broker that is good for tick scalpers EAs. I have realized that these EAs are highly broker sensitive. I used them back in 2017 and enjoyed profits for some weeks because there was no slippage. But over time, my broker started trading against me and I lost all that I had earned. So, I suggest it is better to avoid these and look for brokers with low spreads, low slippage, and fast order execution policies like Interactive Brokers and FxView, so that you don’t end up making losses that you didn’t see coming. Once, I needed help during the initial days to set stop-loss (with Fxview), so I got in touch with their team. Their resolution was prompt.
Pretty different. As I am much into automated trading, I keep on exploring the trading platforms other than MT4, MT5. Discovered tradestation and Acttrader. Found Acttrader better just for the ACTFx. I generally keep a tab on all the brokers and the services they provide especially the underdogs with unique features. Shortlisted Avatrade and Fxview. Fxview is an established broker but to my surprise they weren’t charging high commissions like other top end brokers. Deposits are also quite acceptable for the starters.
I don't know about EA as I don't like it, I scalp manually and can attest to Fxtm, ICMarkets, Fxpro, Fxdd,FxChoice. This brokers instantly copy my trades from my trading station platform to my clients accounts broker just mentioned smoothly, this is so far brokers I could attest for.
