Hi I would like to share my strategy, and hopefully someone can help create an EA or alert.

It is based on 4 hr TMA and m15 trend scalp. The parameters possibly is,
SlopeForUptrend="3.0" SlopeForDowntrend="-3.0"
MidBandFilter: if true - ask below Mid Band for buy, bid above Mid Band for sell
MAX open trade 1 per pair
Closed trades in midband option

Even though the TMA bands are repainting, We only take trades when the slope is met when signal arrow appear.

Buy only below mid band when arrow signal appear and slope is met and closed in mid band option.
Sell only above mid band when arrow signal appear and slope is met and closed in mid band option.
