Requesting guidance on broker for futures, spot, CFDS, options

Hi guys,
i need some guidence. i had developed profitable mt4 and mt5 trading robot and demo trading it successfully.. one ea for DAX and another one for DOW JONES. one of my ea which trades DOW JONES have few issues like pending order triggering bit late or placing orders either pending or market orders. i used icmarket broker.. its working fine but i need my ea to work perfectly or atleast near perfect.

i have never traded futures..am thinking about switching to future and implement my strategy but i dunno what broker to use and i dont understand these terms like options futures cfds spot and etc. so kindly give me direction which broker have less spread/commission.. my ea wont hold trades next day.

i know many of you might skeptic about below performance but its performing much more than that in backtest using real tick data and in demo also its doing good..

-> guide me regarding futures, spots, CFDS, options and their brokers
-> which broker should i use to trade DAX and US30 with little slippage and commission
-> i want to automate things.so broker should allow me to code bots in their platform

thanks a lot.

What exactly was the problem? What kind of pending orders? Limit orders?

they are stoporder.. pending order triggered too late. i chose to place pending stop order instead of market order(slippage issue) but it seems stoporder also have kinda slippage.. i need perfect execution. is it possible? is it broker manipulation or sometimes pending order trigger late when volatile movement happens?

Well, buy stop / sell stop / stop-loss orders are executed as market orders everywhere, so there's no way to avoid negative slippage on those, especially in fast-moving markets.

If you want to totally avoid negative slippage, you can use limit orders for entry and TPs for exit; if you're able to implement them in your trading robots. (That's what I'm doing anyway.) But keep in mind that quite a few forex brokers execute limit orders incorrectly, as market orders; ICmarkets is one of those, unfortunately. So this technique will only work with brokers that respect your limit orders.

ok thank you.. so i have no way other than trying it on these brokers.. lets hope for the best..
